-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?

-    read "If <format> is one of RED, GREEN, BLUE, ALPHA, RGB, RGBA,
-    ABGR_EXT, LUMINANCE, or LUMINANCE_ALPHA, then the index is used to
-    reference 4 tables of color components: PIXEL_MAP_I_TO_R,

-Overview
-
-    Since Mesa allows RGB rendering into drawables with PseudoColor,
-    StaticColor, GrayScale and StaticGray visuals, Mesa needs a colormap
-    in order to compute pixel values during rendering.
-
-    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
-    which allows specification of a colormap.

-    or pixmap.
-

-Dependencies

-    GL_EXT_point_parameters effects the definition of this extension
-    GL_ARB_multitexture effects the definition of this extension
-
-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.

-    Section ???.
-
-    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.

-    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:

+Installing EGCS-Mingw32 Build Revisions:
 
-	a) Open the file archive (either tar.gz or .zip extensions)
+	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.
 
-	b) Decide the directory you want to move the archived files to.
+	a) Move the mingw32.zip file to the top level of the hard drive on your
+system.
 
-	d) Extract the files from the archive.
+	b) Copy all of the Beta 3.08 src/windows files to the src/ directory.
 
-	e) Edit the mingw32.bat file to accomodate your choice of directory structure.
+	b) Open the Winzip file
 
-		%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
+	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	
 
 Running the Build:
 
-	Open your Command Prompt or MS-DOS prompt.
-	Go to your Mesa-3.3 'root' directory
-	At the command line type: mingw32
+	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:
 
-	That's all there is to it.
+	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.
+	At the command line type: mingw32
+		mingw32 is the .bat file that actually does the build.
 
 	Enjoy!

 Mesa Threads README
 -------------------
 
-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:
+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:
   1) POSIX threads (aka pthreads).
   2) Solaris / Unix International threads.
   3) Win32 threads (Win 95/NT).
 
-Support for other thread libraries can be added src/glthread.[ch]
+Here's the current list of targets which enable multithreaded handling
+in Mesa:
 
+  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 guarantee proper operation, it is
+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
 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.

-
-
-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?

-
-
-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
-------------
-
-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):

- * 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.
