+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
+	
+    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.

+
+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.

+			Mesa 4.0 DOS/DJGPP Port v1.0
+			~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+
+
+Description:
+~~~~~~~~~~~~
+
+Well, guess what... this is the DOS port of MESA 4.0, for DJGPP fans... Whoa!
+
+
+
+Legal:
+~~~~~~
+
+MESA copyright applies.
+
+
+
+Installation:
+~~~~~~~~~~~~~
+
+Type "make -f Makefile.DJ" to compile the libraries. Make accepts some options
+which are passed to compiler: the target cpu (CPU=..., default=`pentium') and
+X86 specific options (HAVE_X86=1, HAVE_MMX=1, HAVE_SSE=1, HAVE_3DNOW=1). The
+core library (libGL) requires LFN support during compilation. Also, you must
+have the DXE2 package (available on SimTel.Net, courtesy of Andrew Zabolotny)
+installed in order to build the dynamic modules; if you encounter errors, you
+can fetch a patched version from my web page.
+The demos are not built automagically (see Pitfalls below). To make them, use
+one of the following rules:
+	Static:
+	    gcc -o OUT.exe IN.c -lglut -lglu -lgl
+	Dynamic:
+	    gcc -o OUT.exe -include dmesadxe.h IN.c -ligl -liglu -liglut -ldl
+Usage of the dynamic modules requires three things:
+	- include DMESADXE.H in one of the sources, so references inside
+	  dynamic modules will get resolved (or use `-include' directive)
+	- link against import libraries (libIgl*.a) and LIBDL.A, which will do
+	  the dynamic linkage job for you
+	- put the DXEs somewhere along the library path (LD_LIBRARY_PATH) or
+	  in the current directory
+
+Tested on:
+	CPU:		Intel Pentium w/ MMX @166 MHz
+	Mainboard:	ViA Apollo VP2 w/ 128 MB SDRAM
+	Video card:	Matrox Millenium 2064W w/ 2048 kB WRAM, BIOS v3.0
+	DJGPP:		djdev 2.03 + gcc v3.0.3 + make v3.79
+
+
+
+libGL (the core):
+~~~~~~~~~~~~~~~~~
+
+Of course, MESA 4.0 core sources are required. It will probably work with
+MESA 3.5, but not a chance with earlier versions due to major changes to the
+MESA driver interface and the directory tree. All should compile succesfully.
+
+The driver has its origins in ddsample.c, written by Brian Paul and found by
+me in MESA 3.4.2. I touched almost all the functions, changing the coding
+style :-( Sorry!
+
+Pitfalls:
+1. The current version supports only RGB[A] modes, for it made no sense to me
+   to endorse color-index (aka palette) modes.
+2. Single-buffered is not allowed at all. Until I can find a way to use *REAL*
+   hardware acceleration, it won't get implemented.
+3. Another weird "feature" is that buffer width must be multiple of 4 (I'm a
+   lazy programmer and I found that the easiest way to keep buffer handling at
+   peak performance ;-).
+
+
+
+libGLU:
+~~~~~~~
+
+Mesa GLU sources are required.
+
+
+
+libGLUT (the toolkit):
+~~~~~~~~~~~~~~~~~~~~~~
+
+Well, this "skeletal" GLUT implementation is not mine. Thanks should go to
+Bernhard Tschirren, Mark Kilgard, Brian Paul and probably others (or probably
+not ;-). I only changed it to be self-standing (Allegro-free). The keyboard,
+mouse and timer drivers were inspired from an old project of mine (D3Xl) and
+fixed with some Allegro "infusions"; I deeply thank to Shawn Hargreaves et co.
+
+My keyboard driver used only scancodes, but since GLUT requires ASCII values
+for keys, I borrowed the translation tables (and maybe more) from Allegro.
+Ctrl-Alt-Del (plus Ctrl-Alt-End, for Windows users) will shut down the GLUT
+engine unconditionally: it will raise SIGINT, which in turn will call the
+destructors (let's hope), thus cleaning up your/my mess ;-) NB: since the
+DJGPP guys ensured signal handlers won't go beyond program's space (and since

+
+The mouse driver is far from complete (lack of positioning, drawing, etc),

+The timer is pretty versatile for it supports multiple timers with different

+but timer B will probably loose precision!
+
+As an addition, stdout and stderr are redirected and dumped upon exit. This

+in bulk! A bit of a hack, I know, but I think it's better than to miss them

+Details and Notes

+

-These build files facilitate convenient building of many variants of Mesa,
+
-both as static link libraries (including mesaglu) and as dynamic link
+Karl Schultz
-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):

-    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

-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
-          compatability fix in fxapi.c for in-window rendering using 3Dfx

+                        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

+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
+   glMultiTexCoord2d
+   glMultiTexCoord2dv
+   glMultiTexCoord2f
+   glMultiTexCoord2fv
+   glMultiTexCoord2i
+   glMultiTexCoord2iv
+   glMultiTexCoord2s
+   glMultiTexCoord2sv
+   glMultiTexCoord3d
+   glMultiTexCoord3dv
+   glMultiTexCoord3f
+   glMultiTexCoord3fv
+   glMultiTexCoord3i
+   glMultiTexCoord3iv
+   glMultiTexCoord3s
+   glMultiTexCoord3sv
+   glMultiTexCoord4d
+   glMultiTexCoord4dv
+   glMultiTexCoord4f
+   glMultiTexCoord4fv
+   glMultiTexCoord4i
+   glMultiTexCoord4iv
+   glMultiTexCoord4s
+   glMultiTexCoord4sv
+   glMultTransposeMatrixd
+   glMultTransposeMatrixf
+   glSampleCoverage
+   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.
