+    OpenGL 1.0 or later is required.
+    GLX 1.0 or later is required.
+
+Overview
+
+    The glxCopySubBufferMESA() function copies a rectangular region
+    of the back color buffer to the front color buffer.  This can be
+    used to quickly repaint 3D windows in response to expose events
+    when the back color buffer cannot be damaged by other windows.
+
+IP Status
+
+    Open-source; freely implementable.
+
+Issues
+
+    None.
+
+New Procedures and Functions
+
+    void glXCopySubBufferMESA( Display *dpy, GLXDrawable drawable,
+			       int x, int y, int width, int height );
+
+New Tokens
+
+    None.
+
+Additions to Chapter 3 of the GLX 1.3 Specification (Functions and Errors)
+
+    Add to section 3.3.10 Double Buffering:
+
+    The function
+
+	 void glXCopySubBufferMESA( Display *dpy, GLXDrawable drawable,
+				    int x, int y, int width, int height );
+
+    may be used to copy a rectangular region of the back color buffer to
+    the front color buffer.  This can be used to quickly repaint 3D windows
+    in response to expose events when the back color buffer cannot be
+    damaged by other windows.
+
+    <x> and <y> indicates the lower-left corner of the region to copy and
+    <width> and <height> indicate the size in pixels.  Coordinate (0,0)
+    corresponds to the lower-left pixel of the window, like glReadPixels.
+
+GLX Protocol
+
+    None at this time.  The extension is implemented in terms of ordinary
+    Xlib protocol inside of Mesa.
+
+Errors
+
+    None.
+
+New State
+
+    None.

+Overview
+	
+    Provides a mechanism for DrawPixels and ReadPixels to efficiently
+    transfer depth and stencil image data.  Specifically, we defined new
+    packed pixel formats and types which pack both stencil and depth
+    into one value.
+
+Issues:
+
+    1. Is this the right way to distinguish between 24/8 and 8/24
+       pixel formats?  Should we instead provide both:
+	
+       GL_DEPTH_STENCIL_MESA
+       GL_STENCIL_DEPTH_MESA
+
+       And perhaps just use GL_UNSIGNED_INT, GL_UNSIGNED_SHORT ?
+
+    2. If not, is it correct to use _REV to indicate that stencil
+       preceeds depth in the 1_15 and 8_24 formats?
+
+    3. Do we really want the GL_UNSIGNED_SHORT formats?

+Overview
+
+    Since Mesa allows RGB rendering into drawables with PseudoColor,

+
+    The colormap associated with a window can be queried with normal
+    Xlib functions but there is no colormap associated with pixmaps.
+
+    The glXCreateGLXPixmapMESA function is an alternative to glXCreateGLXPixmap

+
+    The Mesa implementation of GLX allows RGB rendering into X windows and

+    to compute pixel values from RGB values Mesa requires a colormap.
+
+    The function
+
+	GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
+					  Pixmap pixmap, Colormap cmap );
+
+    allows one to create a GLXPixmap with a specific colormap.  The image

+
+Overview
+	
+    This extension modifies the way in which points are rendered,
+    specifically when they're textured.  When SPRITE_POINT_MESA is enabled
+    a point is rendered as if it were a quadrilateral with unique texture
+    coordinates at each vertex.  This extension effectively turns points
+    into sprites which may be rendered more easily and quickly than using
+    conventional textured quadrilaterals.
+
+    When using point size > 1 or attenuated points this extension is an
+    effective way to render many small sprite images for particle systems
+    or other effects.
+
+Issues:
+
+    1. How are the texture coordinates computed?
+
+       The lower-left corner has texture coordinate (0,0,r,q).
+       The lower-right, (1,0,r,q).  The upper-right, (1,1,r,q).
+       The upper-left, (0,1,r,q).
+
+    2. What about texgen and texture matrices?
+
+       Texgen and the texture matrix have no effect on the point's s and t
+       texture coordinates.  The r and q coordinates may have been computed
+       by texgen or the texture matrix.  Note that with a 3D texture and/or
+       texgen that the r coordinate could be used to select a slice in the
+       3D texture.
+
+    3. What about point smoothing?
+
+       When point smoothing is enabled, a triangle fan could be rendered
+       to approximate a circular point.  This could be problematic to
+       define and implement so POINT_SMOOTH is ignored when drawing sprite
+       points.
+
+       Smoothed points can be approximated by using an appropriate texture
+       images, alpha testing and blending.
+
+       POLYGON_SMOOTH does effect the rendering of the quadrilateral, however.
+
+    4. What about sprite rotation?
+
+       There is none.  Sprite points are always rendered as window-aligned
+       squares.  One could define rotated texture images if desired.  A 3D
+       texture and appropriate texture r coordinates could be used to
+       effectively specify image rotation per point.
+
+    5. What about POLYGON_MODE?
+
+       POLYGON_MODE does not effect the rasterization of the quadrilateral.
+
+    6. What about POLYGON_CULL?
+
+       TBD.  Polygon culling is normally specified and implemented in the
+       transformation stage of OpenGL.  However, some rasterization hardware
+       implements it later during triangle setup.
+
+       Polygon culling wouldn't be useful for sprite points since the
+       quadrilaterals are always defined in counter-clockwise order in
+       window space.  For that reason, polygon culling should probably be
+       ignored.
+
+    7. Should sprite points be alpha-attenuated if their size is below the
+       point parameter's threshold size?
+
+    8. Should there be an advertisized maximum sprite point size?
+
+       No.  Since we're rendering the point as a quadrilateral there's no
+       need to limit the size.

+
+    When SPRITE_POINT_MESA is enabled points are rasterized as screen-
+    aligned quadrilaterals.  If the four vertices of the quadrilateral
+    are labeled A, B, C, and D, starting at the lower-left corner and moving
+    counter-clockwise around the quadrilateral, then the vertex and
+    texture coordinates are computed as follows:
+
+      vertex   window coordinate       texture coordinate
+        A      (x-r, y-r, z, w)          (0, 0, r, q)
+        B      (x+r, y-r, z, w)          (1, 0, r, q)
+        C      (x+r, y+r, z, w)          (1, 1, r, q)
+        D      (x-r, y+r, z, w)          (0, 1, r, q)
+
+    where x, y, z, w are the point's window coordinates, r and q are the
+    point's 3rd and 4th texture coordinates  and r is half the point's
+    size.  The other vertex attributes (such as the color and fog coordinate)
+    are simply duplicated from the original point vertex.
+
+    Point size may either be specified with PointSize or computed
+    according to the EXT_point_parameters extension.
+
+    The new texture coordinates are not effected by texgen or the texture
+    matrix.  Note, however, that the texture r and q coordinates are passed
+    unchanged and may have been computed with texgen and/or the texture
+    matrix.
+
+    If multiple texture units are present the same texture coordinate is
+    used for all texture units.
+
+    The point is then rendered as if it were a quadrilateral using the
+    normal point sampling rules.  POLYGON_MODE does not effect the
+    rasterization of the quadrilateral but POLYGON_SMOOTH does.
+
+    POINT_SMOOTH has no effect when SPRITE_POINT_MESA is enabled.

+
+    OpenGL 1.2 is required.
+    The extension is written against the OpenGL 1.2 Specification
+
+Overview
+
+    Provides the application with means to enable and disable logging
+    of GL calls including parameters as readable text. The verbosity
+    of the generated log can be controlled. The resulting logs are
+    valid (but possibly incomplete) C code and can be compiled and 
+    linked for standalone test programs. The set of calls and the 
+    amount of static data that is logged can be controlled at runtime. 
+    The application can add comments and enable or disable tracing of GL 
+    operations at any time. The data flow from the application to GL
+    and back is unaffected except for timing.
+
+    Application-side implementation of these features raises namespace
+    and linkage issues. In the driver dispatch table a simple
+    "chain of responsibility" pattern (aka "composable piepline")
+    can be added.
+
+IP Status
+
+    The extension spec is in the public domain.  The current implementation
+    in Mesa is covered by Mesa's XFree86-style copyright by the authors above.
+    This extension is partially inspired by the Quake2 QGL wrapper.
+
+Issues
+
+ 
+    (1) Is this Extension obsolete because it can
+    be implemented as a wrapper DLL?
+
+      RESOLVED: No. While certain operating systems (Win32) provide linkers 
+      that facilitate this kind of solution, other operating systems
+      (Linux) do not support hierarchical linking, so a wrapper solution
+      would result in symbol collisions.
+      Further, IHV's might have builtin support for tracing GL execution 
+      that enjoys privileged access, or that they do not wish to separate
+      the tracing code from their driver code base.
+
+    (2) Should the Trace API explicitely support the notion of "frames? 
+    This would require hooking into glXSwapBuffers calls as well.
+
+      RESOLVED: No. The application can use NewTraceMESA/EndTraceMESA
+      and TraceComment along with external parsing tools to split the 
+      trace into frames, in whatever way considered adequate.
+
+    (2a) Should GLX calls be traced?
+
+      PBuffers and other render-to-texture solutions demonstrate that
+      context level commands beyond SwapBuffers might have to be
+      traced. The GL DLL exports the entry points, so this would not
+      be out of the question. 
+
+    (3) Should the specification mandate the actual output format?
+
+      RESOLVED: No. It is sufficient to guarantee that all data and commands 
+      will be traced as requested by Enable/DisableTraceMESA, in the order
+      encountered. Whether the resulting trace is available as a readable 
+      text file, binary metafile, compilable source code, much less which 
+      indentation and formatting has been used, is up to the implementation. 
+      For the same reason this specification does not enforce or prohibit
+      additional information added to the trace (statistics, profiling/timing, 
+      warnings on possible error conditions).
+
+    (4) Should the comment strings associated with names and pointer (ranges) 
+    be considered persistent state?
+
+      RESOLVED: No. The implementation is not forced to use this information 
+      on subsequent occurences of name/pointer, and is free to consider it 
+      transient state.
+ 
+    (5) Should comment commands be prohibited between Begin/End?
+
+      RESOLVED: Yes, with the exception of TraceCommentMESA. TraceCommentMESA 
+      is transient, the other commands might cause storage of persistent
+      data in the context. There is no need to have the ability mark names 
+      or pointers between Begin and End.

+Additions to Chapter 5 of the OpenGL 1.2.1 Specification (Special Functions)
+
+    Add a new section:
+
+    5.7 Tracing
+
+    The tracing facility is used to record the execution of a GL program
+    to a human-readable log.  The log appears as a sequence of GL commands
+    using C syntax.  The primary intention of tracing is to aid in program
+    debugging.
+
+    A trace is started with the command
+
+      void NewTraceMESA( bitfield mask, const GLubyte * traceName )
+
+    <mask> may be any value accepted by PushAttrib and specifies a set of
+    attribute groups.  The state values included in those attribute groups
+    is written to the trace as a sequence of GL commands.
+
+    <traceName> specifies a name or label for the trace.  It is expected
+    that <traceName> will be interpreted as a filename in most implementations.
+
+    A trace is ended by calling the command
+
+      void EndTraceMESA( void )
+
+    It is illegal to call NewTraceMESA or EndTraceMESA between Begin and End. 
+
+    The commands
+
+      void EnableTraceMESA( bitfield mask )
+      void DisableTraceMESA( bitfield mask )
+
+    enable or disable tracing of different classes of GL commands.
+    <mask> may be the union of any of TRACE_OPERATIONS_BIT_MESA,
+    TRACE_PRIMITIVES_BIT_MESA, TRACE_ARRAYS_BIT_MESA, TRACE_TEXTURES_BIT_MESA,
+    and TRACE_PIXELS_BIT_MESA.  The special token TRACE_ALL_BITS_MESA
+    indicates all classes of commands are to be logged.
+
+    TRACE_OPERATIONS_BIT_MESA controls logging of all commands outside of
+    Begin/End, including Begin/End.
+  
+    TRACE_PRIMITIVES_BIT_MESA controls logging of all commands inside of
+    Begin/End, including Begin/End.
+ 
+    TRACE_ARRAYS_BIT_MESA controls logging of VertexPointer, NormalPointer,
+    ColorPointer, IndexPointer, TexCoordPointer and EdgeFlagPointer commands.
+
+    TRACE_TEXTURES_BIT_MESA controls logging of texture data dereferenced by
+    TexImage1D, TexImage2D, TexImage3D, TexSubImage1D, TexSubImage2D, and
+    TexSubImage3D commands.
+
+    TRACE_PIXELS_BIT_MESA controls logging of image data dereferenced by
+    Bitmap and DrawPixels commands.
+
+    TRACE_ERRORS_BIT_MESA controls logging of all errors. If this bit is 
+    set, GetError will be executed whereever applicable, and the result will 
+    be added to the trace as a comment. The error returns are cached and 
+    returned to the application on its GetError calls. If the user does not 
+    wish the additional GetError calls to be performed, this bit should not
+    be set.
+    
+    The command
+
+      void TraceCommentMESA( const ubyte* comment )
+
+    immediately adds the <comment> string to the trace output, surrounded
+    by C-style comment delimiters.
+
+    The commands
+
+      void TraceTextureMESA( uint name, const ubyte* comment )
+      void TraceListMESA( uint name, const ubyte* comment )
+
+    associates <comment> with the texture object or display list specified
+    by <name>.  Logged commands which reference the named texture object or
+    display list will be annotated with <comment>.  If IsTexture(name) or
+    IsList(name) fail (respectively) the command is quietly ignored.
+
+    The commands
+
+      void TracePointerMESA( void* pointer, const ubyte* comment )
+
+      void TracePointerRangeMESA( const void* first, 
+                                  const void* last,
+                                  const ubyte* comment ) 
+
+    associate <comment> with the address specified by <pointer> or with
+    a range of addresses specified by <first> through <last>.
+    Any logged commands which reference <pointer> or an address between
+    <first> and <last> will be annotated with <comment>.
+
+    The command
+
+      void TraceAssertAttribMESA( bitfield attribMask )
+
+    will add GL state queries and assertion statements to the log to
+    confirm that the current state at the time TraceAssertAttrib is
+    executed matches the current state when the trace log is executed
+    in the future.
+
+    <attribMask> is any value accepted by PushAttrib and specifies
+    the groups of state variables which are to be asserted.
+
+    The commands NewTraceMESA, EndTraceMESA, EnableTraceMESA, DisableTraceMESA,
+    TraceAssertAttribMESA, TraceCommentMESA, TraceTextureMESA, TraceListMESA, 
+    TracePointerMESA and TracePointerRangeMESA are not compiled into display lists.
+
+
+    Examples:
+
+    The command NewTraceMESA(DEPTH_BUFFER_BIT, "log") will query the state
+    variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE
+    to get the values <test>, <func>, <mask>, and <clear> respectively.
+    Statements equivalent to the following will then be logged:
+
+       glEnable(GL_DEPTH_TEST);   (if <test> is true)
+       glDisable(GL_DEPTH_TEST);  (if <test> is false)
+       glDepthFunc(<func>); 
+       glDepthMask(<mask>);
+       glClearDepth(<clear>);
+   
+
+    The command TraceAssertAttribMESA(DEPTH_BUFFER_BIT) will query the state
+    variables DEPTH_TEST, DEPTH_FUNC, DEPTH_WRITEMASK, and DEPTH_CLEAR_VALUE
+    to get the values <test>, <func>, <mask>, and <clear> respectively.
+    The resulting trace might then look will like this:
+
+    {
+      GLboolean b;
+      GLint i;
+      GLfloat f;
+      b = glIsEnabled(GL_DEPTH_TEST);
+      assert(b == <test>);
+      glGetIntegerv(GL_DEPTH_FUNC, &i);
+      assert(i == <func>);
+      glGetIntegerv(GL_DEPTH_MASK, &i);
+      assert(i == <mask>);
+      glGetFloatv(GL_DEPTH_CLEAR_VALUE, &f);
+      assert(f == <clear>);
+    }
+
+
+Additions to Chapter 6 of the OpenGL 1.2.1 Specification 
+    (State and State Requests)
+
+    Querying TRACE_MASK_MESA with GetIntegerv, GetFloatv, GetBooleanv or
+    GetDoublev returns the current command class trace mask.
+
+    Querying TRACE_NAME_MESA with GetString returns the current trace name.
+
+
+Additions to Appendix A of the OpenGL 1.2.1 Specification (Invariance)
+
+    The MESA_trace extension can be used in a way that does not affect data 
+    flow from application to OpenGL, as well as data flow from OpenGL to 
+    application, except for timing, possible print I/O. TRACE_ERRORS_BIT_MESA
+    will add additional GetError queries. Setting a trace mask with NewTraceMESA
+    as well as use of TraceAssertAttribMESA might cause additional state queries.
+    With the possible exception of performance, OpenGL rendering should not be
+    affected at all by a properly chosen logging operation.
+
+Additions to the AGL/GLX/WGL Specifications
+
+    None.
+
+GLX Protocol
+
+    None. The logging operation is carried out client-side, by exporting
+    entry points to the wrapper functions that execute the logging operation.
+
+Errors
+
+    INVALID_OPERATION is generated if any trace command except TraceCommentMESA
+    is called between Begin and End.
+
+New State
+
+    The current trace name and current command class mask are stored
+    per-context.
+
+New Implementation Dependent State
+
+    None.

-Installing EGCS-Mingw32 Build Revisions:
+Installing GCC-2.95.2/Mingw32 Build:
 
-	To install the makefile and source revisions incorporated with this build
-of the Mesa 3-D Graphics Library, you'll have to use a version of winzip.  I am
-in the process of finding a suitable Win32 compatible tar executable so that if
-you don't have winzip, you can still decompress the files into their respective
-folders/directories.
+	a) Open the file archive (either tar.gz or .zip extensions)
 
-	a) Move the mingw32.zip file to the top level of the hard drive on your
-system.
+	b) Decide the directory you want to move the archived files to.
 
-	b) Copy all of the Beta 3.08 src/windows files to the src/ directory.
+	d) Extract the files from the archive.
+	
+	e) Edit the mingw32.bat file to accomodate your choice of directory structure.
 
-	b) Open the Winzip file
-
-	c) Verify that the files will be properly extracted.
-
-	d) Extract the files with the Winzip "Overwrite" and "Use Folder Names"
-	   options enabled.
-
-	The zip file directory structure extraction defaults to the top level of
-the hard drive where the mingw32.zip file exists unless otherwise instructed by
-you.
-
-	The version of wmesa.c included with the mingw32 archive needs to replace
-the current version of the Beta 3.08 wmesa.c file in order for the egcs-mingw32
-build to work.  This is because the original Win32 stuff assumes that the glut
-utilities are to be installed.  The Glut utilities are not part of the
-egcs-mingw32 build for Beta 3.08.
-
-
-Build Considerations:
-
-	In order to get the build to work, I needed to create a special makefile
-for each library which the Mesa 3-D Graphics Library requires since there is no
-comparable make-config/config on a native windows platform.
-
-	Since I was only creating a few of the possible libraries for 
-Mesa (gl, glu), I only created the new make files in their respective libraries
-src, src-glu).  For libMesaaux.a. you will find a makefile for it in the
-src-aux directory.  libMesatk.a and libglut.a were not ported.
-
-	The build itself is a .bat based build and uses Gnu Make,Version 3.76.1 to
-process the makefiles noted above.  The build must be run from the directory
-where the mingw32.bat file is.  You can get the binary version of Make 3.76.1
-from Jan-Jaap van der Heijden's site in Germany:
-
-	http://agnes.dida.physik.uni-essen.de/~janjaap/mingw32/download.html
-
-	It was necessary to modify some source code, specifically the source code
-in the src-glu directory.  I needed to modify nurbs.c, quadric.c and tess.c in
-order to get them to work using the EGCS-Mingw32 toolchain.
-
-	The original EGCS-Mingw32 Toolchain, is available from:
-
-	http://www.xraylith.wisc.edu/~khan/software/gnu-win32/egcs-mingw32-102.html	
+		%mesaroot%:	This is your root directory (Mesa-3.3)
+		%mesasrc%:	This is the Mesa-3.3 src directory (Mesa-3.3\src)
+		%mesalib%:	This is where the build will put libGL.a and libGLU.a
 
 Running the Build:
 
-	Ok, now that we've got the basics out of the way, follows is all you need
-to do in order to build the EGCS-Mingw32 version of libMesaGL.a and libMesaGLU.a:
-
-	Open your Command Prompt/Dos prompt.
-	Go to your Mesa-3.0 beta 'root' directory.
-		This is the same directory that the Mesa mingw32.zip file was
-		originally stored in if you've installed the Mesa-3.0 beta 3-D
-		Graphics Library source as outlined in the "readme" file included
-		with the Mesa-3.0 beta distribution.
+	Open your Command Prompt or MS-DOS prompt.
+	Go to your Mesa-3.3 'root' directory
 	At the command line type: mingw32
-		mingw32 is the .bat file that actually does the build.
+
+	That's all there is to it.
 
 	Enjoy!

 Mesa Threads README
 -------------------
 
-Mesa 2.6 is the starting point for an effort to make Mesa 
-safe in multithreaded applications.  The files src/mthreads.c and
-src/mthreads.h provide a platform independent threads API which Mesa
-uses internally to provide thread-safe operation.  At present the mthreads
-code supports three thread APIS:
+Thread safety was introduced in Mesa 2.6 by John Stone and
+Christoph Poliwoda.
+
+It was redesigned in Mesa 3.3 so that thread safety is
+supported by default (on systems which support threads,
+that is).  There is no measurable penalty on single
+threaded applications.
+
+NOTE that the only _driver_ which is thread safe at this time
+is the OS/Mesa driver!
+
+
+At present the mthreads code supports three thread APIS:
   1) POSIX threads (aka pthreads).
   2) Solaris / Unix International threads.
   3) Win32 threads (Win 95/NT).
 
-Here's the current list of targets which enable multithreaded handling
-in Mesa:
+Support for other thread libraries can be added src/glthread.[ch]
 
-  linux-386-pthread    for Linux w/ Intel assembly and linuxthreads
-  sunos5-thread        for Suns with SunOS 5.x, using Solaris threads
-  sunos5-pthread       for Suns with SunOS 5.[56] using POSIX threads
-  sunos5-gcc-thread    for Suns with SunOS 5.x and GCC, using Solaris threads
-  sunos5-gcc-pthread   for Suns with SunOS 5.[56] and GCC, using POSIX threads
 
-In order to use Mesa with a multithreaded application, Mesa must be compiled
-using one of the thread-enabled configurations.  In cases where a platform
-supports multiple APIs which are acceptable to Mesa, Mesa must be built
-with the same threads API as the application in order for things to work
-properly.  For example, Solaris >= 2.5 support both POSIX threads and
-Sun's own threads API.  In order to guarantee proper operation, it is
+In order to guarantee proper operation, it is
 necessary for both Mesa and application code to use the same threads API.
 So, if your application uses Sun's thread API, then you should build Mesa
 using one of the targets for Sun threads.
 
-Since this effort is still very much a work in progress, not all 
-aspects of Mesa are thread safe.  As of this release (Mesa 2.6) only the
-osmesa drivers have been made MT-safe.  As work continues, other drivers
-such as the X11 drivers will also incorporate MT-safe features.

-
-*** What's New
-
-- Updated for Mesa 3.1beta3/CVS. Debug and Release command-line builds of
-  Mesa, fxMesa, GLU, GLUT and all sample programs DLL-based. Manual
-  executions tests with minimum requisite results (aka: things looked like
-  I expected them to).
-
-  What did you expect, complete regression testing maybe?
-
-- NASM build support. Any file in the project coded as a .S file will
-  automatically be recognized and built as a NASM-source assember file.
-
-  To enable building using NASM, set the environment variable NASM to
-  indicate that command to execute to run nasm on a file. If NASM is in
-  your command search path then all this needs be set to is 'nasmw' -
-  otherwise you will need to include the complete drive and directory path.
-
-  NASM may be retrieved here: http://www.web-sites.co.uk/nasm/
-
-- DevStudio projects suspended for compatability reasons: projects modified
-  by DevStudio 6 are not compatible with DevStudio 5.
-
-  These will slowly be rebuilt and put into CVS as I can.
-
-- Build environment change: The Glide SDK is no longer assumed to be in
-  the global INCLUDE/LIB environment vars, it is required that you set the
-  value 'GLIDE2X' as either an environment variable pointing to your Glide
-  SDK install directory or that you configure that as a build option to
-  nmake.exe when building fxmesagl32.  Examples:
-
-    nmake /f nmake.mak GLIDE2X=g:\sdk\glide2x fxmesagl32
-
-          <or>
-
-    nmake /f nmake.mak GLIDE2X=g:\sdk\glide2x allfx
-
-          <or>
-
-    nmake /f nmake.mak GLIDE2X=g:\sdk\glide2x progs.3dfx.demos
-
-  The DevStudio workspace files for 3Dfx OpenGL require the definition of
-  GLIDE2SDK as an environment variable pointing to where your copy of the
-  Glide SDK has been installed. Adding this to your AUTOEXEC.BAT would do
-  so (change the directories to match):
-
-       SET GLIDE2SDK=G:\SDK\GLIDE2X

-*** General Information
-
-These build files facilitate convenient building of many variants of Mesa,
-both as static link libraries (including mesaglu) and as dynamic link
-libraries that in some cases may be used as "drop-in" replacements for
-OpenGL32.DLL on both Windows95 and Windows NT.
-
-The construction of the Win32 command-line build files and projects has
-been something of a pet project of mine, and is based upon my own
-"standard" Win32 build environment as supplied by the "nmake.mif" file.
-They have been tested under Windows95 OSR2, Windows NT 4.0SP3, and Windows
-NT 5.0 beta 1.  The libraries that they generated have been tested (via the
-demo programs) in a *limited* fashion on the above three systems, including
-the 3Dfx versions.
-
-The reason I went with command-line build environment instead of the more
-convenient IDE-based project files is for two reasons: 1. These appear to
-have some amount of portability between versions (the nmake syntax hasn't
-changed much since Microsoft C 7.0) while the IDE project files seem to
-change drastically each version. and 2. These are readable with any ascii
-editor and such are better self-documentation of the file relationships for
-more people such that it will facilitate supporting other Win32 compilers.
-
-While these files only deal with building for x86 targeted code it *should*
-be possible to add the necessary logic to them to build for the other MSVC
-supported CPU targets, I simply have no hardware to test them on nor the
-alternative compilers to build with.
-
-*** Prerequisites for use
-
-1. You must have a 32-bit Microsoft compiler installed. I have tested
-this with Visual C 5.0 (SP3) and Visual C 4.2, but with minor
-(possibly no) modification to the nmake.mak and nmake.mif files this
-sequence should work on Visual C 2.0 also. The workspace files
-(mesalib.dsw and mesademos-*.dsw) and their included project files
-(*.dsp) are specific to the DevStudio IDE - I have made no attempt at
-building a VC4 IDE project set as I do not use that any more.  Note
-that the VC workspace files NO LONGER use NORE are dependant upon the
-nmake.mak and nmake.mif files for construction of definition (*.DEF)
-and resource (*.RC) files.
-
-*** Visual C 4.x Users Warning ****
-
-Note that early editions of VC4 do NOT have header files current enough
-for use building this code base. If you are using VC4 you will either need
-to get an update to version 4.2 *or* you may download the Platform SDK
-directly from Microsoft's web site (www.microsoft.com) and update your
-build environment that way.
-
-*** Visual C 4.x Users Warning ****
-
-2. You must have the PATH, INCLUDE, and LIB environment variables set
-properly. With VC5 you can easily get this by executing the VCVARS32.BAT
-file that was created for you upon installation. It is found in the
-DevStudio\VC\BIN directory, wherever you installed DevStudio. VC4 provides
-a similar batch file in it's BIN directory also.
-
-3. (optional) If you're going to build for 3Dfx/Voodoo you will need to
-have previously installed the Glide SDK version 2.3 or later, if I
-recall. This may be retrieved from www.3dfx.com for no money and some
-download time. ;-) These build files assume that you have the Glide SDK
-added to the respective environment variables (LIB and INCLUDE).
-
-4. (optional) If you're going to build for S3/Virge you will need the S3
-Developers Toolkit which may be downloaded from www.s3.com for the price of
-registering on-line and some time. NOTE: I can build the s3mesa.dll file to
-completion, however the compilation of s3mesa.c currently generates a large
-amount of compiler warnings and between that and the fact that I can not at
-all test it I can make no claims to it's ability to execute.  Again, like
-the 3Dfx version before this, these build files assume you have the S3Dtk H
-and LIB files in the path of their respective environment variables.
-Note 2: As of Mesa3.0beta6 I have build files, both command-line and IDE,
-which should be able to build the s3mesa code base if it weren't for updates
-being required in the S3 DD code support (Mesa-3.0/src/s3 directory).
-
-I advise putting any include and lib files for secondary toolkits (Glide,
-S3Tk, whatever) in their respective environment variables *before* the
-Microsoft-assigned default values.
-
-*** FAQ: Frequenty Asked Questions and Other Important Information ***
-
-- When running the 3Dfx demos under Windows NT, they crash on exit, what's
-  up?
-
-  This is apparently a problem in Glide itself. The workaround is to go to
-  your C:\WINNT\SYSTEM32 directory and rename the file FXOEM2X.DLL to
-  FXOEM2X.DL_ to prevent Glide from loading and initializing it upon
-  startup.  This is known to be an issue with cards that do not have "TV
-  out" and is known to cause crashes on Diamond Monster II 8M and 3Dfx
-  Reference boards, all using 3Dfx Reference Drivers version 2.53. Other
-  hardware/driver combinations will also likely exhibit this behavior.
-
-- I'm having a problem building Mesa for static library linking.
-
-  This was caused by some incomplete testing on my part, and a fix is now
-  available in the form of an add-on to the base Mesa 3.0 release.  The
-  file to get is:
-
-       via FTP download from: iris.ssec.wisc.edu
-         you want to go here: /pub/Mesa/patches_to_3.0/
-        you want to get file: Mesa-3.0-w32-static-fixes.tar.gz
-
-  This required a minor addition to INCLUDE/GL for a clean solution, the
-  file "include/gl/mesa_wgl.h" is automatically included by
-  "include/gl/gl.h" when a Win32 non-DLL build is in progress to provide
-  prototypes for the various wgl functions.
-
-  The only remaining hitch in this setup is that the 3Dfx build is not yet
-  running as a static build, because of problems with conflicts in
-  existance of the various GDI functions like ChoosePixelFormat,
-  etc. *sigh*
-
-  Anyway, the "allstatic" target now works as expected and builds all
-  book/sample/demos programs to boot. ;^)
-
-- How do I get fxMesa to render in a window on the desktop instead of only
-  full-screen?
-
-  Use the Microsoft Windows fxMesa-in-a-window hack!
-
-  Seriously, if you want fxMesaGL to render using the 3Dfx Voodoo1 or
-  Voodoo2 hardware into a window on the desktop then all you need to do is
-  set the MESA_WGL_FX environment variable to anything other than
-  "fullscreen" and it will render into a window.  If you wish to go
-  fullscreen then you only need to NOT have the environment variable, or
-  have it set to "fullscreen".  You may also switch at runtime between
-  fullscreen-mode and windowed by pressing ALT-ENTER on the keyboard
-  (unless the application using Mesa does something with those keystrokes,
-  of course).
-
-  As of 8/13/98 this should be running a LOT better for more people as a
-  low-compatability item was cleaned up which prevented it from working on
-  many (most?) display drivers under Windows 9x.
-
-- I have my 3Dfx card hooked to it's own monitor and I want the output to
-  stay on even if I switch to another program, is this possible?
-
-  If the Glide environment variable SST_DUALHEAD is set to '1' then fxMesa
-  will never disable the Voodoo output on a Voodoo1 or Voodoo2 display
-  regardless of whether the fxMesa application is "current" or not. This
-  works regardless of whether it's rendering using the window hack
-  mentioned above or not.
-
-- I want to run the Mesa demos on my Intel740 card using it's own OpenGL
-  acceleration, how do I do this?
-
-  Build GLUT standalone for use with system OpenGL and GLU drivers!
-
-  The Command-line project supports building all test/demo programs against
-  these drivers also! This allows you full use of GLUT on Windows using
-  hardware accelerated OpenGL. Wheee! This includes the "3dfx/demos"
-  directory of which only two programs will not run on "standard"
-  opengl. Note that there are a few of the sample programs which will NOT
-  work without Mesa as they directly call into Mesa instead of using the
-  extension mechanism.
-
-*** Included programs that exhibit unfortunate or bad behavior
-
-- demos/bounce - doesn't run on high-colors screens?  It's requesting an
-  INDEX display from GLUT and that fails on my true-color desktop. Changing
-  this to _RGB let's the program work, but it doesn't display
-  properly. This is probably just an idiosyncracy of my machine though, as
-  if I test the program using GLUT for System OpenGL on my Intel740 OpenGL
-  accelerated machine it's just hunky-dory.
-
-- demos/glutfx - runs, but crashes on exit (but not on my Intel740 machine)
-
-- demos/texobj - runs, but crashes on exit if ESC is pressed. Exits cleanly
-  if the Close box on the window frame is pressed with the mouse. Go figure.
-
-- book/aaindex - doesn't run, can't get pixel format, because it wants an
-  INDEX display maybe (but is okay on my Intel740 machine)?
-
-- most of the book/* demos don't respond to ESC being pressed.
-
-- 3dfx/demos/* - all demos run, however they all crash on exit. I've traced
-  this so far as to determine the call it's happening with. The crash comes
-  from within Glide during the processing of the grGlideShutdown() call, as
-  in invalid memory reference exception. I'm wondering if this is because
-  of some state or processing not being completed before the call. Dunno,
-  but putting grSstIdle() in just before grGlideShutdown() does NOT fix the
-  problem.
-
-- 3dfx/demos/tunnel2 - does not run on my system even with SLI mode
-  disabled. Hmmmm, maybe I need to disconnect my Voodoo2 cards?
-
-*** Important Notes and Changing Default values
-
-- The optimizer settings have been manually reworked in both command line
-  and DevStudio IDE files to hopefully prevent possible irrational code on
-  the part of the code generator.  Formerly, it was configured for "/Ox",
-  now it is configured for safer handling at a slight potential performance
-  cost. This may not be required for Visual Studio 6 but I can't test that
-  (yet).
-
-- These files build with the code targeted for Pentium processors and
-  8-byte structure padding.
-
-- The IDE-built programs seem to be "happier" in that the command line
-  build of the 3Dfx demo "fire" will grenade on exit (?). Otherwise pretty
-  much everything may be built with either interface.
-
-- The currently configured Mesa version is 3.1, and MesaDemos version is
-  the same. To change this permanently you will need to edit NMAKE.MAK and
-  change the lines that look like this (they start o/a line 116):
-
-    # Currently, Mesa is at rev 3.1 ...
-    #
-    !IF "$(MESAVER)" == ""
-    MESAVER=3.1
-    !ENDIF
-
-    # used in building all of the resource files for the Mesa DLLs
-    #
-    !IF "$(MESAFILEVER)" == ""
-    MESAFILEVER=3,1,0,0
-    !ENDIF
-
-- Currently the build files are configured to be used from a Win32
-  directory that is included inside the main Mesa-3.1 heirarchy.
-
-- The build files are smart enough to find the files for the core lib, glu,
-  glut, and the various demo programs if they are unpacked in the current
-  Mesa-3.1 heirarchy, like this:
-
-    \Mesa-3.1
-    \Mesa-3.1\src
-    \Mesa-3.1\src-glu
-    \Mesa-3.1\src-glut
-    \Mesa-3.1\Win32
-    \Mesa-3.1\samples
-    \Mesa-3.1\demos
-    \Mesa-3.1\book
-    \Mesa-3.1\3Dfx\demos
-
-    ... should work.  This arose because my initial build tests for the
-    demo files were done before MesaDemos 2.6 had been released.
-
-- With the exception of the static link libraries generated by this file
-  set (mesagl.lib, mesaglu.lib, mesaglut.lib) all DLLs and executables are
-  built against the "Multithreaded DLL" runtime - this means that they
-  require MSVCRT.DLL or MSVCRTD.DLL in the path to execute.
-
-  ** CHANGED 8/11/98 ***
-
-  Note also that the demos are all built aginst the "OpenGL32, GLU32, and
-  GLUT32" and as such they are fairly agnostic wrt: building against Mesa
-  for CPU-rendering, Mesa-for-3Dfx, Mesa-for-S3, or System OpenGL.
-
-  If you want to build them for use on your system and your display card
-  provides full OpenGL acceleration (Permedia, Intel740, Intergraph,
-  whatever) then you only need to build GLUT prior to building any of the
-  demo programs. For convenience, the GLUT project is included in each of
-  the demo projects Workspace files for the DevStudio IDE builds BUT it is
-  not automatically built - you still need to build it first manually.
-
-  Note that if you have GLUT already installed on your system (gl/glut.h in
-  yoru INCLUDE path, glut32.lib/glut32d.lib in your LIB path, and the DLL
-  in your PATH) then you do NOT need to build GLUT prior to the test
-  programs.
-
-- The 3Dfx build of Mesa has primarily been tested with Quake 2 and it runs
-  (mostly) fine on my PC (take that for what you want it)...
-
-  ** CHANGED  8/11/98 ***
-
-  There is still something going on that causes Glide to crash on shutdown,
-  when I run fxMesa under Windows NT, however it does not appear to occur
-  under Windows 9x on either Voodoo1 or Voodoo2 cards. *sigh*
-
-- I can not test the S3 build as I have no machines available with Virge
-  based display cards.
-
-- The multithreaded test code is *not* built as it requires pthreads and I
-  have as of yet spent not time trying to get that running. The latest word
-  that I saw WRT threading support on win32 was that they are intending to
-  support it natively within Win32 - so I'm waiting it out until they get
-  it done.
-
-- Similarly, the 'xdemos' are not currently built because I haven't gotten
-  around to building the client libs for native win32 and getting it all
-  setup for use.
-
-*** Output Files
-
-All final output files (DLL/LIB) are placed in the Mesa-3.1/lib directory,
-with the exception of the fxMesaGL32 build which is placed in
-Mesa-3./lib/FX and the executable images which are placed in their source
-directories.
-
-To be able to execute the various test programs, you will need to copy the
-requisite DLL files into the same directory as the EXE files. Note that
-most of the 3Dfx/demos/* programs WILL run with the non-FX build of Mesa -
-just very slowly. The two programs which are hard-linked with the FX build
-and will not run without it are "glbpaltx" which uses "gl3DfxSetPaletteEXT"
-directly instead of via the extensions mechanism and "tunnel2" which uses
-"fxMesaSelectCurrentBoard" API for selecting between multiple 3Dfx cards
-installed in one system. Likewise, "paltex" directly uses the
-"glColorTableEXT" extension and thus may not run on anything except
-Mesa. If these applications used the proper extension mechanism they could
-then be used on more than "just" fxMesa to good effect (for example, the
-rest of the "3Dfx/demos" run just peachy on the Intel740 card in my test
-machine) under WinNT.
-
-Because I'm anal about my computer and it's organization, and I like to
-prevent collision between builds, each of the subprojects has their own
-intermediate file directory inside .\win32\release (for example, when
-building mesagl.lib all of it's intermediate files will be found in
-.\win32\release\lib.mesagl).  This makes it very easy to cleanup as you
-only need to remove .\win32\release.
-
-*** Okay, Enough, how do I build with this stuff already Ted!
-
-Okay, no major calamity here. The basic way to use the project file is to
-call it via NMAKE from the command line. The format is:
-
-    nmake[.exe] /f nmake.mak [options] [target]
-
-The most likely [options] values you will use may be any combination of the
-following:
-
-    DEBUG=1 or DEBUG=0
-    USE_CRTDLL=1 or USE_CRTDLL=0
-
-    Note that all three of these options are OFF by default.
-
-The [target] includes but is not limited to the following (for full details
-please peruse the NMAKE.MAK and NMAKE.MIF files - but be warned that
-NMAKE.MIF is rather large and sometimes hard to follow):
-
-    --- convenience targets ---
-
-    all                 - builds everything
-    libfiles            - builds all linking library files
-    progs               - builds all executable images
-
-    --- library files, static and dynamic ---
-
-    mesagl              - static lib build of Mesa core.
-    mesaglu             - static lib build of MesaGLU core.
-    mesaglut            - static lib build of Mesa GLUT core.
-
-    mesagl32            - dynamic lib build of Mesa core.
-
-    mesaglu32           - dynamic lib build of GLU core, generates
-                          GLU32.DLL and/or GLU32d.DLL.
-
-    mesaglut32          - dynamic lib build of GLUT core, generates
-                          GLUT32.DLL and/or GLUT32d.dll.
-
-    --- hardware accelerated mesa builds ---
-
-    fxmesagl32          - builds Mesa for use on top of the 3Dfx
-                          Glide runtime libs
-
-    s3mesagl32          - builds mesa for use on top of the S3
-                          'S3Tk' runtime libs.
-
-    --- executable images ---
-
-    progs.book          - builds all programs in \book directory
-    progs.demos         - builds all programs in \demos directory
-    progs.samples       - builds all programs in \samples directory
-
-        These targets generate all of the programs in their respective
-        directories and link the executables against OpenGL32.DLL,
-        GLU32.DLL, and GLUT32.DLL (or their debug equivalents).
-
-    progs.3dfx.demos    - builds all programs in \3dfx\demos directory
-
-        This target generates the 3Dfx/Demo executables, linking them
-        against GLUT32.DLL, GLU32.DLL, OPENGL32.DLL and are thus NOT
-        hard-bound to using Mesa per-se as you can simply NOT build the
-        Mesa core and GLU libraries.
-
-   --- Microsoft/SGI OpenGL-based GLUT and Demo program builds ----
-
-   *** IMPORTANT SAFETY TIP: If you're going to build these variants of
-       GLUT then DO NOT build any other target libraries in this package
-       first, OR from the command line run the "nmake /f nmake.mak clean"
-       command first!  This is because generation of the GLUT for SGI
-       OpenGL target libraries conflicts in naming with the static build
-       libraries of Mesa and it's supporting GLUT build.
-
-   Currently, you may build GLUT as either GLUT32.DLL or GLUT.DLL for
-   use running against either Microsoft or SGI OpenGL for Window,
-   respectively.  This allows for the general use of GLUT 3.7 on Windows
-   systems with fully compliant OpenGL.
-
-   You can build the GLUT DLL files either with the command line by
-   issuing either of these commands:
-
-        nmake /f nmake.mak glut.sysgl
-
-        <or>
-
-        nmake /f nmake.mak glut.sgigl
-
-   OR by using the DevStudio MesaLib Worksapce build the GLUT_SGIGL or
-   GLUT_SYSGL projects within the DevStudio IDE.
-
-   Unfortunately, the only way to build the test programs against this
-   build of GLUT is via the command line, and I will NOT be making
-   duplicate demo program projects for the IDE as it's just not worth it,
-   sorry.
-
-   To build the test programs against either MS or SGI OpenGL, you do so
-   via either of these two commands:
-
-        nmake /f nmake.mak progs.sysgl
-
-        <or>
-
-        nmake /f nmake.mak progs.sgigl
-
-   To use the GLUT-for-system-OpenGL in your own programs, you need to do
-   three things by way of preparation, after building GLUT of course:
-
-         1. Copy include\gl\glut.h to somewhere in your %INCLUDE% path, one
-            likely candidate location would be in your
-            "DevStudio\VC\INCLUDE\GL" directory.
-
-         2. Copy the linking libraries to somewhere in your %LIB% path, one
-            likely candidate location would be in your "DevStudio\VC\LIB"
-            directory. The linking libraries you need to copy are as
-            follows:
-
-                .\Release\GLUT32.LIB
-                .\Release\GLUT.LIB
-                .\Debug\GLUT32.LIB
-                .\Debug\GLUT.LIB
-
-        3. Copy the runtime libraries to somewhere in your %PATH%, one
-           likely candidate location would be in WINDOWS\SYSTEM. the files
-           that you should copy are as follows:
-
-                .\Release\GLUT32.DLL
-                .\Release\GLUT32.PDB
-                .\Release\GLUT.DLL
-                .\Release\GLUT.PDB
-                .\Debug\GLUT32d.DLL
-                .\Debug\GLUT32d.PDB
-                .\Debug\GLUTd.DLL
-                .\Debug\GLUTd.PDB
-
-Some examples are in order ...
-
-    ... build all dynamic-link libs using MSVCRT.DLL for C runtime:
-
-        nmake /f nmake.mak USE_CRTDLL=1 alldynamic
-
-    ... To build all library variants and all test and demonstration
-        programs with the default settings you do this:
-
-        nmake /f nmake.mak all
-
-    ... to build all static link libs and nothing else you do this:
-
-        nmake /f nmake.mak allstatic
-
-    ... to build all non-accelerated dynamic link libs you do this:
-
-        nmake /f nmake.mak alldynamic
-
-    ... to build all 3Dfx targeted dynamic link libs you do this:
-
-        nmake /f nmake.mak allaccel
-
-    ... to build all S3 Virge targetd dynamic link libs you do this:
-
-        nmake /f nmake.mak alls3
-
-    ... to build all libraries, static and dynamic, in all versions
-        you do this:
-
-        nmake /f nmake.mak libfiles
-
-    ... to subsequently build all demo and test programs you do this:
-
-        nmake /f nmake.mak progs
-
-    ... to cleanup all intermediate files you do this:
-
-        nmake /f clean
-
-You get the picture. (I hope) ;^)  You may also specify specify
-single targets in a convenient fashion. The rule is simple, any of the
-above named lib files, static or dynamic, may be built by providing it's
-name on the command line as the target. Examples:
-
-    ... to build only Mesa as OpenGL32.DLL ...
-
-        nmake /f nmake.mak opengl32
-
-    ... to build only Mesa on top of the 3Dfx Glide API ...
-
-        nmake /f nmake.mak fxMesaGL32
-              <or>
-        nmake /f nmake.mak fxMesaGL
-
-    ... to build only Mesa on top of the S3 Toolkit ...
-
-        nmake /f nmake.mak s3MesaGL32
-              <or>
-        nmake /f nmake.mak s3mesaGL

-          dependant upon (thanks to Keven T. McDonnell for finding
-          that there was this particular bug). I also updated the
-          build files for 2.6beta6.
-2/8/98  - added DevStudio workspace and project files for all lib
-          files and some test programs. Updated readme.win32.
-6/25/98 - initial revision for Mesa 3.0, does not include IDE files,
-          not everything is running. *sigh*
-7/20/98 - Mesa 3.0beta6 rev of all build files, all libs built and
-          minimally tested, all demo programs built and minimally
-          tested to within limits of my PC. ;^) Eveything looks
-          MUCH better now ...
-7/30/98 - Minor updates/edits based upon feedback from
-          Eero Pajarre <epajarre@koti.tpo.fi>. These updates include a fix

-          properly on my system. It runs, just *very* slowly and with *no*
-          textures. Hmmm. Doesn't make any difference whether Quake is set
-          to use 8-bit textures or not.
-8/13/98 - Lots of build cleanups, minor bug fixes in fxwgl.c, and

+File: docs/README.WIN32
+
+Last updated: Nov 29, 2001 - Karl Schultz - kschultz@users.sourceforge.net
+
+Quick Start
+
+If you have Microsoft Visual C++ 6.0 installed, simply go to the top directory
+of the Mesa distribution and type 'nmake -f Makefile.win NODEBUG=1' for
+an optimized build.
+
+Details and Notes
+
+- Building Mesa as noted above should visit and build the following:
+  src        MesaGL.dll, MesaGL.lib, osmesa.dll, osmesa.lib
+  si-glu     MesaGLU.dll, MesaGLU.lib
+  src-glut   glut32.dll, glut32.lib
+  demos      a handful of demo executables.
+
+- After building, you can copy the above DLL files to a place in your PATH
+  or to the demos directory if you just want to give the demos a try.
+  The DLL and LIB files are copied to the ./lib directory.  The makefile
+  creates this directory if it does not already exist.
+
+- The make targets 'clean' and 'clobber' will remove objects and libraries.
+  But the files in ./lib are never cleaned.
+
+- The make target 'install' will take its best shot at copying DLL files,
+  LIB files, and headers to the right places.  I strongly suggest that
+  you examine the makefiles to make sure that 'install' doesn't do anything
+  that you can't live with.
+
+- The makefiles are designed to work with Microsoft's NMAKE, and do,
+  unfortunately, have some Microsoft-specific things in them.  If you
+  would like to use gcc or some other build tools like the Cygnus tools,
+  then you will have to hack the makefiles to make them work with your
+  tools.  I'm sorry about this; I wasn't motivated to make this any
+  different, but if you end up modifying the makefiles for your tools,
+  you can send me the changes and I can apply the changes to the 
+  source tree.
+
+- There are no Microsoft Visual Studio project files.  However, these
+  should be very easy to create.  One can use the compiler and linker
+  options found in the makefiles to make quick progress in creating
+  projects.
+
+- The DLL files are built so that the external entry points use the
+  stdcall calling convention.
+
+- Static LIB files are not built.  The LIB files that are built with
+  the current makefiles are the linker import files associated with
+  the DLL files.  If static LIB's are desired, it should not be too
+  difficult to modify the makefiles to generate them.
+
+- The si-glu sources are used to build the GLU libs.  This was done
+  mainly to get the better tessellator code.
+
+- The osmesa driver builds and should work on Windows as well as
+  any other platform.
+
+- The Windows driver (in src/Windows) builds and runs at least at
+  a minimal level.  I modified this driver to work with the new
+  Mesa 4.0 code and driver architecture, but I did not do a great
+  deal of optimization and testing.  There are many opportunities
+  for optimization, many of which can be done by coding more specific
+  paths for the rasterizers.  See src/osmesa/osmesa.c for some good
+  examples.
+
+- There is DirectDraw support in the Windows driver, updated by
+  Daniel Slater.  You'll need to uncomment the #define DDRAW line
+  in src/Windows/wmesadef.h and add ddraw.lib to the list of libraries
+  in src/Makefile.win.  On some systems, you will acheive significantly
+  higher framerates with DirectDraw.
+
+- Some of the more specialized code like FX drivers, stereo, and
+  parallel support isn't compiled or tested.  I left much of this
+  code alone, but it may need some work to get it 'turned on' again.
+
+- No assembly code is compiled or assembled.  Again, this may need
+  some work to turn it back on or use it again.
+
+If you have a Windows-related build problem or question, it is
+probably better to direct it to me (kschultz@users.sourceforge.net),
+rather than directly to the other Mesa developers.  I will help you
+as much as I can.  I also monitor the Mesa mailing lists and will
+answer questions in this area there as well.

+                        WindML Driver for Mesa 4.0
+
+
+Requirements
+------------
+
+Tornado 2 + WindML, Cumulative Patchs are recommended. 
+  
+I suppose you have a valid WindML installation. Double buffer hardware
+gives better performance than double buffer software so if you can
+compile your WindML driver with this option, just do it. I/O
+redirection is adviced in target server.
+
+
+Tested on
+---------
+
+During the development, my main target was a CoolMonster:
+- Video card: CT69000
+- CPU: PENTIUM 266MHz
+
+and my host a Windows NT + Tornado 2.
+
+
+Installation
+------------
+
+1. Mesa sources must be in root directory (C:\)
+
+2. Add the following line to your torVars.bat:
+set MESA_BASE=C:\Mesa
+
+OR copy the new torVars.bat in your bin path:
+c:/Mesa/src/ugl/tornado/torVars.sample -> 
+/mnt/nt/Tornado/host/x86-win32/bin/torVars (for example)
+
+3. In a command prompt:
+$ torVars
+$ cd c:\Mesa
+$ make -f Makefile.ugl CPU=PENTIUM
+
+Take a long while...
+
+5. Include all the files from ugldemos folder to build some downloadable
+   application modules
+
+4. Download UGL/Mesa object files on target
+
+For example via the WindShell:
+ld < c:\Tornado\target\lib\objMesaGL.o
+ld < c:\Tornado\target\lib\objMesaUGL.o
+ld < c:\Tornado\target\lib\objMesaGLU.o
+ld < c:\Tornado\target\lib\objGLUTshapes.o
+ld < c:\Tornado\target\lib\objMesaOS.o
+
+You can put the previous lines in a file and use:
+< filename
+
+6. Download the application modules.
+
+7. In WindShell, run:
+-> uglalldemos
+
+During the show some messages will appear, it provides some useful
+information on key management.
+
+
+Coding
+------
+
+Sample Usage:
+
+In addition to the usual ugl calls to initialize UGL, (may be find an
+input driver), you must do the following to use the UGL/Mesa interface:
+
+1. Call uglMesaCreateContext() to create a UGL/Mesa rendering context,
+   given the display format.
+
+2. Call uglMesaMakeCurrent() to bind the UGL/Mesa buffers to an
+   UGL/Mesa Context and to make the context the current one.
+
+3. Make gl* calls to render your graphics.
+
+4. Use uglMesaSwapBuffers() when double buffering to swap front/back buffers.
+
+5. Before the UGL is destroyed, call MesaDestroyContext().
+
+6. Before exiting, call if required uglEventQDestroy and then
+   uglDeinitialize();
+
+Limitations
+-----------
+
+I found the following limitations in my driver :
+ - Color Indexed management is only in 8 bits
+ - It's possible to mix UGL/OpenGL application with a software
+   double buffer

 Installation
 ============
 
-To compile the library, first type 'make' alone to see the list of system
-configurations currently supported.  If you see your configuration on the
-list, type 'make <config>'.  Most popular Unix/X workstations are currently
-supported.
+There are two ways to compile Mesa on Unix/X11 systems:
+
+1. The old way:
+    First type 'make' alone to see the list of system
+    configurations currently supported.  If you see your configuration on the
+    list, type 'make <config>'.  Most popular Unix/X workstations are currently
+    supported.
+
+    If your system configuration is not listed by 'make', you'll have to modify
+    the top-level Makefile and Make-config files.  There are instructions in
+    each file.
+
+
+2. The new way:
+    Type './configure' and then 'make'.  This uses GNU autoconfig.
+    See docs/INSTALL for more details.
+
 
 The top-level makefile will execute the makefiles in a number of sub-
-directories.  When finished, the Mesa libraries will be in the Mesa-2.6/lib/
+directories.  When finished, the Mesa libraries will be in the Mesa-4.0.1/lib/
 directory.  A few GLUT demos in the demos/ directory should be ready to run.
 
 If you also downloaded and unpacked the demos there should be executables
 in the "xdemos/", "samples/", and "book/" directories for you to try out.
-If you only want to compile the contents of one subdirectory you can 'cd'
-to that directory and type 'make <config>' there.
-
-If your system configuration is not listed by 'make', you'll have to modify
-the top-level Makefile and Make-config files.  There are instructions in
-each file.
 
 If you have compilation problems you should try to fix them and return the
 patches to the author.
 
 
+Notes on assembly language optimizations:
+
+   When using the old-style Makefiles, you can specify a configuration
+   that uses X86 assembly language optimizations (linux-3dnow for example).
+
+   The detection of MMX, 3DNow!, PIII/SSE, etc capability is done at
+   runtime.  That means you can compile Mesa for 3DNow! optimizations
+   even if you don't have an AMD CPU.
+
+   However, your Linux binutils and assembler must understand the
+   special instructions in order to compile them.  If you have
+   compilation problems, try upgrading your binutils.
+
+

    After you've compiled Mesa and tried the demos I recommend the following
    procedure for "installing" Mesa.

+
+                             PLEASE READ!!!!
+
+
+New copyright
+-------------
+
+Mesa 3.1 will be distributed under an XFree86-style copyright instead
+of the GNU LGPL.
+
+
+New directories
+---------------
+
+All documentation files are now in the docs/ directory.
+All shell scripts are now in the bin/ directory.
+
+
+New library names
+-----------------
+
+Formerly, the main Mesa library was named libMesaGL.so (or libMesaGL.a)
+and the GLU library was named libMesaGLU.so (or libMesaGLU.a).
+
+Now, the main library is named libGL.so (or libGL.a) and the GLU library
+is named libGLU.so (or libGLU.a).
+
+The change allows Mesa to be more easily substituted for OpenGL.
+Specifically, the linker/loader on some Unix-like systems won't
+allow libMesaGL.so to be used instead of libGL.so if the application
+was linked with the former.
+
+Warning: if you have another OpenGL implementation installed on your
+system (i.e. you have another OpenGL libGL.so) you'll have to be
+carefull about which library (OpenGL or Mesa) you link against.  Be
+aware of -L linker flags and the value of the LD_LIBRARY_PATH environment
+variable.
+
+
+New library versioning
+----------------------
+
+Previously, the Mesa GL library was named libMesaGL.so.3.0
+To better support Linux/OpenGL standards, the Mesa GL library is now
+named libGL.so.1.2.030100  This indicates version 1.2 of the OpenGL spec
+and Mesa implementation 3.1.0
+
+In the long term this will allow better interoperability with other
+OpenGL implementations, especially on Linux.  In the short term,
+OpenGL apps may have to be relinked to use the new library naming.
+
+
+
+New makefiles
+-------------
+
+The old Makefiles found in the various directories have been renamed
+to Makefile.X11 in order to prevent filename collisions with autoconfig-
+generated Makefiles.
+
+The top-level Makefile simply includes Makefile.X11
+If your top-level Makefile get's overwritten/destroyed you can restore
+it by copying Makefile.X11 to Makefile
+
+
+New extensions
+--------------
+
+GL_EXT_stencil_wrap
+	Implements two new stencil operations: GL_INCR_WRAP_EXT and
+	GL_DECR_WRAP_EXT which allow stencil increment and decrement
+	without clamping.
+
+GL_INGR_blend_func_separate
+	Allows specification of blend factors for RGB and Alpha independently.
+	(INGR = Intergraph)
+
+GL_ARB_multitexture
+	Multiple simultaneous textures.  (ARB = Architecture Review Board)
+
+GL_NV_texgen_reflection
+	nVidia texgen extension for better reflection mapping.
+
+GL_PGI_misc_hints
+	Assorted transformation hints.
+
+GL_EXT_compiled_vertex_array
+	Compiled vertex arrays.
+
+GL_EXT_clip_volume_hint
+	Allows one to disable clip volume (frustum) testing.
+
+
+
+Extensions removed
+------------------
+
+GL_EXT_multitexture - obsolete in favor of GL_ARB_multitexture
+
+
+
+Config file
+-----------
+
+By default, /etc/mesa.conf will be read when Mesa starts.  This
+file controls default hints, enable/disable of extensions, and
+more.  See the CONFIG file for documentation.
+
+
+
+Optimizations
+-------------
+
+Keith Whitwell has contributed significant optimizations to Mesa's
+vertex transformation code.  Basically, the whole transformation
+stage of Mesa has been rewritten.
+
+It's impossible to give a speedup factor.  You'll just have to
+try your app and see how it performs.
+
+
+
+Device Driver changes
+---------------------
+
+A bunch of new device driver functions have been added.  See src/dd.h
+Keith Harrison contributed many of them.  I've been planning on adding
+a bunch of functions like these to make writing hardware drivers easier.
+More such function will probably be added in the near future.
+
+
+
+Miscellaneous
+-------------
+
+util/glstate.c has some handy functions for debugging.  Basically, it
+offers a simple function for printing GL state variables.  It's not
+finished yet.  There's a LOT more GLenum records to be added (see the
+code).  Anyone want to help?

+
+                             PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.3) designate new developmental releases.
+Even numbered versions (such as 3.2.1) designate stable releases.
+
+Mesa 3.3 has a undergone many internal changes since version 3.2
+and features a lot of new extensions.  3.3 is expected to be pretty
+stable, but perhaps not as stable as 3.2 which has been used by
+thousands of users over the past months.
+
+Everyone is encouraged to try Mesa 3.3.  Bugs should be reported to
+the Mesa bug database on www.sourceforge.net.
+
+
+
+Header file / GLenum changes
+----------------------------
+
+The gl.h and glu.h headers now use #defines to define all GL_* tokens
+instead of C-language enums.  This change improves Mesa/OpenGL
+interoperability.
+
+
+
+New API dispatch code
+---------------------
+
+The core Mesa gl* functions are now implemented with a new dispatch
+(jump table) which will allow simultaneous direct/indirect rendering.
+
+The code is found in the glapi*.[ch] files.
+
+Of interest:  the actual "glFooBar" functions are generated with
+templatized code defined in glapitemp.h and included by glapi.c
+The glapitemp.h template should be reusable for all sorts of OpenGL
+projects.
+
+The new dispatch code has also optimized with x86 assembly code.
+This optimization eliminates copying the function arguments during
+dispatch.
+
+
+
+New thread support
+------------------
+
+Thread support in Mesa has been rewritten.  The glthread.[ch] files
+replace mthreads.[ch].  Thread safety is always enabled (on platforms
+which support threads, that is).  There is virtually no performance
+penalty for typical single-thread applications.  See the glapi.c
+file for details.
+
+The Xlib driver (XMesa) is now thread-safe as well.  Be sure to
+call XInitThreads() in your app first.  See the xdemos/glthreads.c
+demo for an example.
+
+
+
+Make configuration changes
+--------------------------
+
+If you use the old-style (non GNU automake) method to build Mesa note
+that several of the configuration names have changed:
+
+   Old name        New name
+   -------------   ----------------
+   linux-elf       linux
+   linux           linux-static
+   linux-386-elf   linux-386
+   linux-386       linux-386-static
+   etc.
+
+
+
+New extensions
+--------------
+
+GL_ARB_transpose_matrix
+	Adds glLoadTransposeMatrixARB() and glMultTransposeMatrixARB()
+        functions.
+
+GL_ARB_texture_cube_map
+	For cube-based reflection mapping.
+
+GL_EXT_texture_add_env
+	Adds GL_ADD texture environment mode.
+	See http://www.berkelium.com/OpenGL/EXT/texture_env_add.txt
+
+GL_EXT_texture_lod_bias
+	Allows mipmapped texture blurring and sharpening.
+
+GLX_EXT_visual_rating extension
+	This extension has no effect in stand-alone Mesa (used for DRI).
+
+GL_HP_occlusion_test
+	Used for bounding box occlusion testing (see demos/occlude.c).
+
+GL_SGIX_pixel_texture / GL_SGIS_pixel_texture
+	Lets glDraw/CopyPixels draw a texture coordinate image.
+
+GL_SGI_color_matrix
+	Adds a color matrix and another set of scale and bias parameters
+	to the glDraw/CopyPixels paths.
+
+GL_SGI_color_table
+	Adds additional color tables to the glDraw/Read/CopyPixels paths.
+
+GL_EXT_histogram
+	Compute histograms for glDraw/Read/CopyPixels.
+
+GL_EXT_blend_func_separate
+	This is the same as GL_INGR_blend_func_separate.
+
+GL_ARB_texture_cube_mapping
+	6-face cube mapping, nicer than sphere mapping
+
+GL_EXT_texture_env_combine
+	For advanced texture environment effects.
+
+
+Documentation for all these functions can be found at
+http://oss.sgi.com/projects/ogl-sample/registry/
+
+
+
+GLX_SGI_make_current_read functionality
+---------------------------------------
+
+The functionality of this extension is needed for GLX 1.3 (and required
+for the Linux/OpenGL standards base).
+
+Implementing this function required a **DEVICE DRIVER CHANGE**.
+The old SetBuffer() function has been replaced by SetReadBuffer() and
+SetDrawBuffer().  All device drivers will have to be updated because
+of this change.
+
+The new function, glXMakeContextCurrent(), in GLX 1.3 now works in Mesa.
+The xdemos/wincopy.c program demonstrates it.
+
+
+
+Image-related code changes
+--------------------------
+
+The imaging path code used by glDrawPixels, glTexImage[123]D,
+glTexSubImage[123], etc has been rewritten.  It's now faster,
+uses less memory and has several bug fixes.  This work was
+actually started in Mesa 3.1 with the glTexImage paths but has now
+been carried over to glDrawPixels as well.
+
+
+
+Device driver interface changes
+-------------------------------
+
+Added new functions for hardware stencil buffer support:
+   WriteStencilSpan
+   ReadStencilSpan
+   WriteStencilPixels
+   ReadStencilPixels
+
+
+Removed old depth buffer functions:
+   AllocDepthBuffer
+   DepthTestSpan
+   DepthTestPixels
+   ReadDepthSpanFloat
+   ReadDepthSpanInt
+
+
+Added new depth buffer functions:
+   WriteDepthSpan
+   ReadDepthSpan
+   WriteDepthPixels
+   ReadDepthPixels
+
+   These functions always read/write 32-bit GLuints.  This will allow
+   drivers to have anywhere from 0 to 32-bit Z buffers without
+   recompiling for 16 vs 32 bits as was previously needed.
+
+
+New texture image functions
+   The entire interface for texture image specification has been updated.
+   With the new functions, it's optional for Mesa to keep an internal copy
+   of all textures.  Texture download should be a lot faster when the extra
+   copy isn't made.
+
+Misc changes
+   TexEnv now takes a target argument
+   Removed UseGlobalTexturePalette (use Enable function instead)
+
+
+Also added
+   ReadPixels
+   CopyPixels
+
+
+The SetBufffer function has been replaced by SetDrawBuffer and
+SetReadBuffer functions.  This lets core Mesa independently
+specify which buffer is to be used for reading and which for
+drawing.
+
+The Clear function's mask parameter has changed.  Instead of
+mask being the flags specified by the user to glClear, the
+mask is now a bitmask of the DD_*_BIT flags in dd.h.  Now
+multiple color buffers can be specified for clearing (ala
+glDrawBuffers).  The driver's Clear function must also
+check the glColorMask glIndexMask, and glStencilMask settings
+and do the right thing.  See the X/Mesa, OS/Mesa, or FX/Mesa
+drivers for examples.
+
+
+The depth buffer changes shouldn't be hard to make for existing
+drivers.  In fact, it should simply the code.  Be careful with
+the depthBits value passed to gl_create_context().  1 is a bad
+value!  It should normally be 0, 16, 24, or 32.
+
+
+gl_create_framebuffer() takes new arguments which explicitly tell
+core Mesa which ancillary buffers (depth, stencil, accum, alpha)
+should be implemented in software.  Mesa hardware drivers should
+carefully set these flags depending on which buffers are in the
+graphics card.
+
+
+
+Internal constants
+------------------
+
+Point and line size range and granularity limits are now stored
+in the gl_constants struct, which is the Const member of GLcontext.
+The limits are initialized from values in config.h but may be
+overridden by device drivers to reflect the limits of that driver's
+hardware.
+
+Also added constants for NumAuxBuffers and SubPixelBits.
+
+
+
+OpenGL Conformance
+------------------
+
+Mesa now passes all the OpenGL 1.1 conformance tests, except for
+antialiased lines.  AA lines fail on some, but not all, the tests.
+In order to fix the remaining failures, a new AA line algorithm will
+be needed (which computes coverage values for end-point fragments).
+This will be done for Mesa 3.5/3.6.
+
+
+
+OpenGL 1.2 GL_ARB_imaging subset
+--------------------------------
+
+Mesa 3.3 implements all the features of GL_ARB_imaging except for
+image convolution.  This will (hopefully) be done for Mesa 3.5/3.6.

+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.5) designate new developmental releases.
+Even numbered versions (such as 3.4) designate stable releases.
+
+The biggest change in Mesa 3.5 is a complete overhaul of the source
+code in order to make it more modular.  This was driven by the DRI
+hardware drivers.  It simplifies the DRI drivers and opens the door
+to hardware transform/clip/lighting (TCL).  Keith Whitwell can take
+the credit for that.
+
+
+
+Driver Support
+--------------
+
+The device driver interface in Mesa 3.5 has changed a lot since Mesa 3.4
+Not all of the older Mesa drivers have been updated.  Here's the status:
+
+Driver			Status
+----------------------	-----------
+XMesa (Xlib)		updated
+OSMesa (off-screen)	updated
+FX (3dfx Voodoo1/2)	updated
+SVGA			updated
+GGI			not updated
+Windows/Win32		not updated
+DOS/DJGPP		not updated
+BeOS			not updated
+Allegro			not updated
+D3D			not updated
+DOS			not updated
+
+We're looking for volunteers to update the remaining drivers.  Please
+post to the Mesa3d-dev mailing list if you can help.
+
+
+
+GLU 1.3
+-------
+
+Mesa 3.5 includes the SGI Sample Implementation (SI) GLU library.
+This version of GLU supports the GLU 1.3 specification.  The old
+Mesa GLU library implemented the 1.1 specification.  The SI GLU
+library should work much better.
+
+You'll need a C++ compiler to compile the SI GLU library.  This may
+be a problem on some systems.
+
+
+
+New Extensions
+--------------
+
+GL_EXT_convolution
+	Adds image convolution to glRead/Copy/DrawPixels/TexImage.
+
+GL_ARB_imaging
+	This is the optional imaging subset of OpenGL 1.2.
+	It's the GL_EXT_convolution, GL_HP_convolution_border_modes,
+	GL_EXT_histogram, GL_EXT_color_table, GL_EXT_color_subtable
+	GL_EXT_blend_color, GL_EXT_blend_minmax, GL_EXT_blend_subtract
+	and GL_SGI_color_matrix extensions all rolled together.
+	This is supported in all software renderers but not in all
+	hardware drivers (3dfx for example).
+
+GL_ARB_texture_compression
+	This is supported in Mesa but only used by the 3dfx DRI drivers
+	for Voodoo4 and later.
+
+GL_ARB_texture_env_add
+	This is identical to GL_EXT_texture_env_add.
+
+GL_NV_blend_square
+	Adds extra blend source and dest factors which allow squaring
+	of color values.
+
+GL_EXT_fog_coord
+	Allows specification of a per-vertex fog coordinate instead of
+	having fog always computed from the eye distance.
+
+GL_EXT_secondary_color
+	Allows specifying the secondary (specular) color for each vertex
+	instead of getting it only from lighting in GL_SEPARATE_SPECULAR_COLOR
+	mode.
+
+GL_ARB_texture_env_combine
+	Basically the same as GL_EXT_texture_env_combine
+
+GL_ARB_texture_env_add extension
+	Texture addition mode.
+
+GL_ARB_texture_env_dot3 extension
+	Dot product texture environment.
+
+GL_ARB_texture_border_clamp
+	Adds GL_CLAMP_TO_BORDER_ARB texture wrap mode
+
+GL_SGIX_depth_texture, GL_SGIX_shadow and GL_SGIX_shadow_ambient
+	Implements a shadow casting algorithm based on depth map textures
+
+GL_SGIS_generate_mipmap
+	Automatically generate lower mipmap images whenever the base mipmap
+	image is changed with glTexImage, glCopyTexImage, etc.
+
+
+
+libOSMesa.so
+------------
+
+libOSMesa.so is a new library which contains the OSMesa interface for
+off-screen rendering.  Apps which need the OSMesa interface should link
+with both -lOSMesa and -lGL.  This change was made so that stand-alone
+Mesa works the same way as XFree86/DRI's libGL.
+
+
+
+Device Driver Changes / Core Mesa Changes
+-----------------------------------------
+
+The ctx->Driver.LogicOp() function has been removed.  It used to
+be called during state update in order to determine if the driver
+could do glLogicOp() operations, and if not, set the SWLogicOpEnabled
+flag.  Drivers should instead examine the LogicOp state themselves
+and choose specialized point, line, and triangle functions appropriately,
+or fall back to software rendering.  The Xlib driver was the only driver
+to use this function.  And since the Xlib driver no longer draws
+points, lines or triangles using Xlib, the LogicOp function isn't needed.
+
+The ctx->Driver.Dither() function has been removed.  Drivers should
+detect dither enable/disable via ctx->Driver.Enable() instead.
+
+The ctx->Driver.IndexMask() and ctx->Driver.ColorMask() functions
+are now just called from glIndexMask and glColorMask like the other
+GL state-changing functions.  They are no longer called from inside
+gl_update_state().  Also, they now return void.  The change was made
+mostly for sake of uniformity.
+
+The NEW_DRVSTATE[0123] flags have been removed.  They weren't being used
+and are obsolete w.r.t. the way state updates are done in DRI drivers.
+
+
+Removed obsolete gl_create_visual() and gl_destroy_visual().
+
+Renamed functions (new namespace):
+
+old				new
+gl_create_framebuffer		_mesa_create_framebuffer
+gl_destroy_framebuffer		_mesa_destroy_framebuffer
+gl_create_context		_mesa_create_context
+gl_destroy_context		_mesa_destroy_context
+gl_context_initialize		_mesa_context_initialize
+gl_copy_context			_mesa_copy_context
+gl_make_current			_mesa_make_current
+gl_make_current2		_mesa_make_current2
+gl_get_current_context		_mesa_get_current_context
+gl_flush_vb			_mesa_flush_vb
+gl_warning			_mesa_warning
+gl_compile_error		_mesa_compile_error
+
+
+All the drivers have been updated, but not all of them have been
+tested since I can't test some platforms (DOS, Windows, Allegro, etc).
+
+
+X/Mesa Driver
+-------------
+
+The source files for the X/Mesa driver in src/X have been renamed.
+The xmesa[1234].c files are gone.  The new files are xm_api.c,
+xm_dd.c, xm_line.c, xm_span.c and xm_tri.c.
+
+
+
+Multitexture
+------------
+
+Eight texture units are now supported by default.
+
+
+
+OpenGL SI related changes
+-------------------------
+
+In an effort to make Mesa's internal interfaces more like the OpenGL
+SI interfaces, a number of changes have been made:
+
+1. Importing the SI's glcore.h file which defines a number of
+interface structures like __GLimports and __GLexports.
+
+2. Renamed "struct gl_context" to "struct __GLcontextRec".
+
+3. Added __glCoreCreateContext() and __glCoreNopDispatch() functions.
+
+4. The GLcontext member Visual is no longer a pointer.
+
+5. New file: imports.c to setup default import functions for Mesa.
+
+
+
+
+16-bit color channels
+---------------------
+
+There's experimental support for 16-bit color channels (64-bit pixels)
+in Mesa 3.5.  Only the OSMesa interface can be used for 16-bit rendering.
+Type "make linux-osmesa16" in the top-level directory to build the
+special libOSMesa16.so library.
+
+This hasn't been tested very thoroughly yet so please file bug reports
+if you have trouble.
+
+In the future I hope to implement support for 32-bit, floating point
+color channels.

+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.3) designate new developmental releases.
+Even numbered versions (such as 3.4) designate stable releases.
+
+Mesa version 4.0 signifies two things:
+
+  1. A stabilization of the 3.5 development release
+  2. Implementation of the OpenGL 1.3 specification
+
+
+Note that the Mesa major version number is incremented with the OpenGL
+minor version number:
+
+   Mesa 1.x  ==  OpenGL 1.0
+   Mesa 2.x  ==  OpenGL 1.1
+   Mesa 3.x  ==  OpenGL 1.2
+   Mesa 4.x  ==  OpenGL 1.3
+
+
+
+New Features
+------------
+
+Mesa 3.5 already had all the new features of OpenGL 1.3, implemented as
+extensions.  These extensions were simply promoted to standard features:
+
+   GL_ARB_multisample
+   GL_ARB_multitexture
+   GL_ARB_texture_border_clamp
+   GL_ARB_texture_compression
+   GL_ARB_texture_cube_map
+   GL_ARB_texture_env_add
+   GL_ARB_texture_env_combine
+   GL_ARB_texture_env_dot3
+   GL_ARB_transpose_matrix
+
+In Mesa 4.0 the functions defined by these extensions are now available
+without the "ARB" suffix.  For example, glLoadTransposeMatrixf() is now
+a standard API function.  The new functions in OpenGL 1.3 and Mesa 4.0 are:
+
+   glActiveTexture
+   glClientActiveTexture
+   glCompressedTexImage1D
+   glCompressedTexImage2D
+   glCompressedTexImage3D
+   glCompressedTexSubImage1D
+   glCompressedTexSubImage2D
+   glCompressedTexSubImage3D
+   glGetCompressedTexImage
+   glLoadTransposeMatrixd
+   glLoadTransposeMatrixf
+   glMultiTexCoord1d
+   glMultiTexCoord1dv
+   glMultiTexCoord1f
+   glMultiTexCoord1fv
+   glMultiTexCoord1i
+   glMultiTexCoord1iv
+   glMultiTexCoord1s
+   glMultiTexCoord1sv

+   glMultiTexCoord2fv
+   glMultiTexCoord2i
+   glMultiTexCoord2iv
+   glMultiTexCoord2s

+   glMultiTexCoord3d
+   glMultiTexCoord3dv

+   glMultiTexCoord3fv

+   glMultiTexCoord4fv
+   glMultiTexCoord4i

+   glMultiTexCoord4s
+   glMultiTexCoord4sv

+   glMultTransposeMatrixf

+   glSamplePass
+
+
+GLX 1.4 is the companion to OpenGL 1.3.  The only new features in GLX 1.4
+are support for multisampling and the GLX_ARB_get_proc_address extension.
+glXGetProcAddress() is the only new function in GLX 1.4.
+
+
+
+Multisample and Texture Compression
+-----------------------------------
+
+The OpenGL 1.3 specification allows the multisample and texture compression
+features to essentially be no-ops.  For example, if you query for multisample
+support you'll find none, but the API functions work.
+
+Similarly, texture compression is not implemented by any of the software
+drivers but you can specify a generic compressed texture format (like
+GL_COMPRESSED_RGBA) to glTexImage2D and it'll be accepted.
+
+
+
+Device Drivers
+--------------
+
+Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on the
+device driver.  If the driver enables all the ARB extensions which are part
+of OpenGL 1.3 then glGetString(GL_VERSION) will return "1.3".  Otherwise,
+it'll return "1.2".
+
+A number of Mesa's software drivers haven't been actively maintained for
+some time.  We rely on volunteers to maintain many of the drivers.
+Here's the current status of all included drivers:
+
+
+Driver			Status
+----------------------	---------------------
+XMesa (Xlib)		implements OpenGL 1.3
+OSMesa (off-screen)	implements OpenGL 1.3
+FX (3dfx Voodoo1/2)	implements OpenGL 1.3
+SVGA			implements OpenGL 1.3
+Wind River UGL		implements OpenGL 1.3
+Windows/Win32		implements OpenGL 1.3
+GGI			needs updating
+DOS/DJGPP		needs updating
+BeOS			needs updating
+Allegro			needs updating
+D3D			needs updating
+DOS			needs updating
+
+Special thanks go to Karl Schultz for updating the Windows driver.
+
+The XFree86/DRI drivers	have not yet been updated to use Mesa 4.0 as of
+September 2001, but that should happen eventually.
+
+

+INTRODUCTION
+------------
+
+This directory is usually included in the Mesa demos distribution or
+in the GLUT distribution.
+
+I have written the demos included in this directory mainly for showing
+the capabilities of the Mesa library when using the Voodoo driver.
+However all the demos are written using the GLUT and OpenGL so they
+work with any GLUT/OpenGL platform (tested: Linux+Mesa+Voodoo driver,
+Linux+Mesa+X11 driver, Win95+Mesa+Voodoo driver and SGI Onyx IR thanks
+to Mark Kilgard).
+
+All the demos make an heavy use of texture mapping, blending, etc. so
+you _need_ some kind of hardware support for the OpenGL otherwise they
+will run at ~1fps. You need also a OpenGL 1.1 compliant library.
+
+You can find some screenshot of these demos at
+http://www-hmw.caribel.pisa.it/fxmesa/fxdemos.hmtl
+
+Write me if you find some bug in the demos.

+
+A BRIEF DESCRIPTION OF THE DEMOS
+--------------------------------
+
+
+IPERS
+-----
+
+Sources: ipers.c image.c
+
+A nice spinning fractal object.
+
+
+RAY
+---
+
+Sources: ray.c
+
+I'm using ray tracing to dynamically generate texture maps with
+specular, diffuse, shadows, and mirror colors. Each frame the texture
+maps of the plane and of the sphere are partially updated.  With this
+technique you can obtain true mirrors, shadows, specular highlights,
+bump mapping, etc. in realtime.  This demo is really CPU intensive
+(~25fps on a PentiumII@300MHz with a Pure3D).  Support on-the-fly
+switching between fullscreen and in-window rendering under Linux/Mesa
+(start your X server in 16 bpp mode and press the spacebar).
+
+
+TUNNEL
+------
+
+Sources: tunnel.c image.c sources.c
+Data: bw.rgb tile.rgb
+
+The model was designed and prelighted with Alias|Wavefront
+PowerAnimator V8. Triangle strips were built with a tool written by me
+and then statically included in the sources.  This demo doesn't
+require the ZBuffer and use antialiased polygons.  Support on-the-fly
+switching between fullscreen and in-window rendering under Linux/Mesa
+(start your X server in 16 bpp mode and press the spacebar).
+
+
+TUNNEL2
+------
+
+Sources: tunnel2.c image.c sources.c
+Data: bw.rgb tile.rgb
+
+The some tunnel demo but with two output channels. A nice
+example of the Mesa/Voodoo support for multiple boards in
+the some PC.
+
+
+TEAPOT
+------
+
+Sources: teapot.c image.c dteapot.c shadow.c
+Data: bw.rgb tile.rgb
+
+The shadow is drawn projecting the teapot geometry over the plane. All
+other light effects are drawn using the standard OpenGL capabilities.
+Support on-the-fly switching between fullscreen and in-window
+rendering under Linux/Mesa (start your X server in 16 bpp mode and
+press the spacebar).
+
+
+FIRE
+----
+
+Sources: fire.c image.c
+Data: s128.rgb tree2.rgb
+
+The demo use a small particle system to draw some nice visual effect.
+You can interactively change many parameters of the particle system
+and you can choose the number of particles at the startup ('fire
+4000').  This demo should be called fountain.  Support on-the-fly
+switching between fullscreen and in-window rendering under Linux/Mesa
+(start your X server in 16 bpp mode and press the spacebar).
+
+
+TERRAIN
+-------
+
+Sources: mesaland.c
+
+This demo is base on another demo written by Mikael SkiZoWalker.  I
+have added the capabilities to freely fly around, view culling and
+some nice color.  Support on-the-fly switching between fullscreen and
+in-window rendering under Linux/Mesa (start your X server in 16 bpp
+mode and press the spacebar).
+
+
+GLTEST
+------
+
+Sources: gltest.c
+
+This is a simple benchmark suite that I'm using in the development of
+the Mesa/Voodoo driver. Type 'gltest >my.res' and you will get some
+data about the performances of your OpenGL. Follow the results with my
+PC (Linux+Mesa-2.6+PentiumII@300MHz+Pure3D):

+the other example in order to show the capabilities of the
+gl3DfxSetPaletteEXT() (it used only by GLQuake and Quake2).

+ * How this works:
+ * 1. We load the image into a 2D texture.
+ * 2. We generate a sequence of RGB images in which the R component
+ *    is really the S texture coordinate and the G component is really
+ *    the T texture coordinate.
+ *    By warping the mapping from R to S and G to T we can get non-linear
+ *    distortions.
+ * 3. Draw the warped image (a 2-D warping function) with pixel texgen
+ *    enabled.
+ * 4. Loop over the warped images to animate.
+ *
+ * The pixel texgen extension can also be used to do color-space
+ * conversions.  For example, we could convert YCR to RGB with a
+ * 3D texture map which takes YCR as the S,T,R texture coordinate and
+ * returns RGB texel values.
+ *
+ * You can use this extension in (at least) two ways:
+ * 1. glDrawPixels w/ color space conversion/warping
+ * 2. glDrawPixels to spatially warp another image in texture memory
+ *
+ * We're basically using glDrawPixels to draw a texture coordinate image.
