What do you need ?
------------------
- WindML Driver for Mesa 3.5
+ WindML Driver for Mesa 4.0
Requirements
- Mesa 3.5.1 Unix/X11 Information
+ Mesa 4.0 Unix/X11 Information
The top-level makefile will execute the makefiles in a number of sub-
-directories. When finished, the Mesa libraries will be in the Mesa-3.5/lib/
+directories. When finished, the Mesa libraries will be in the Mesa-4.0/lib/
directory. A few GLUT demos in the demos/ directory should be ready to run.
If you also downloaded and unpacked the demos there should be executables

+ Mesa 4.0 release notes
+
+ September ??, 2001
+
+ PLEASE READ!!!!
+
+
+
+Introduction
+------------
+
+Mesa uses an even/odd version number scheme like the Linux kernel.
+Odd numbered versions (such as 3.3) designate new developmental releases.
+Even numbered versions (such as 3.4) 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
+GGI needs updating
+Windows/Win32 needs updating
+DOS/DJGPP needs updating
+BeOS needs updating
+Allegro needs updating
+D3D needs updating
+DOS needs updating
+
+The XFree86/DRI drivers have not yet been updated to use Mesa 4.0 as of
+September 2001, but that should happen eventually.
+
+
+
+Other Changes

+
+See the VERSIONS file for more details about bug fixes, etc. in Mesa 4.0.
