- * - applied some patch for the Voodoo Rush
- *

- * - the driver is now able to take advantage of the ClipMask[],
- * ClipOrMask and ClipAndMask information also under Windows
- * - introduced a new function in the Mesa driver interface
- * ClearColorAndDepth(). Now the glClear() function is
- * 2 times faster (!) when you have to clear the color buffer
- * and the depth buffer at some time
- * - written the first version of the fxRenderVB() driver
- * function
- * - optimized the glTexImage() path
- * - removed the fxMesaTextureUsePalette() support
- * - fixed a bug in the points support (thanks to David Farrell
- * for an example of the problem)
- * - written the optimized path for glSubTexImage(),
- * introduced a new function in the Mesa driver interface
- * TexSubImage(...)
- * - fixed a bug for glColorMask and glDepthMask
- * - the wbuffer is not more used. The Voodoo driver uses
- * a standard 16bit zbuffer in all cases. It is more consistent
- * and now GLQuake and GLQuake2test work also with a GL_ZTRICK 0
- * - the driver is now able to take advantage of the ClipMask[],
- * ClipOrMask and ClipAndMask information (under Linux);
- * - rewritten the setup_fx_units() function, now the texture

- * support is still missing). The LinuxGLQuake console correctly
- * fade in/out and transparent water of GLQuake2test works fine
- * - written the support for the env. var. FX_GLIDE_SWAPINTERVAL
- * - found a bug in the Mesa core. There is a roundup problem for
- * color values out of the [0.0,1.0] range
- *
- * Wonko <matt@khm.de>
- * - fixed a Voodoo Rush related problem in the fxwgl.c
- *
- * Daryll Strauss <daryll@harlot.rb.ca.us>
- * - written the scissor test support
- *
- * V0.20 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
- * - written the closetmmanger() function in order to free all the memory
- * allocated by the Texture Memory Manager (it will be useful
- * when the support for multiple contexts/boards will be ready)
- * - now the Voodoo driver runs without printing any information,
- * define the env. var. MESA_FX_INFO if you want to read some
- * information about the hardware and some statistic
- * - written a small workaround for the "GLQuake multiplayer white box bug"
- * in the setup_fx_units() funxtions. I'm already rewriting
- * this function because it is the source of nearly all the current
- * Voodoo driver problems
- * - fixed the GLQuake texture misalignment problem (the texture
- * coordinates must be scaled between 0.0 and 256.0 and not
- * between 0.0 and 255.0)
- * - written the support for the GL_EXT_shared_texture_palette
- * - some small change for supporting the automatic building of the
- * OpenGL32.dll under the Windows platform
- * - the redefinition of a mipmap level is now a LOT faster. This path
- * is used by GLQuake for dynamic lighting with some call to glTexSubImage2D()
- * - the texture memory is now managed a set of 2MB blocks so
- * texture maps can't be allocated on a 2MB boundary. The new Pure3D
- * needs this kind of support (and probably any other Voodoo Graphics
- * board with more than 2MB of texture memory)
- *
- * Brian Paul (brianp@elastic.avid.com) Avid Technology
- * - added write_monocolor_span(), fixed bug in write_color_span()

- * - written the 3Dfx Global Palette extension for GLQuake
- * - written the support for the GL_EXT_paletted_texture (it works only with GL_RGBA
- * palettes and the alpha value is ignored ... this is a limitation of the
- * the current Glide version and Voodoo hardware)
- * - fixed the amount of memory allocated for 8bit textures
- * - merged the under construction v0.19 driver with the Mesa 2.5
- * - finally written the support for deleting textures
- * - introduced a new powerful texture memory manager: the texture memory
- * is used as a cache of the set of all defined texture maps. You can
- * now define several MB of texture maps also with a 2MB of texture memory
- * (the texture memory manager will do automatically all the swap out/swap in
- * work). The new texture memory manager has also
- * solved a lot of other bugs/no specs compliance/problems
- * related to the texture memory usage. The texture
- * manager code is inside the new fxmesa3.c file
- * - broken the fxmesa.c file in two files (fxmesa1.c and fxmesa2.c)
- * and done some code cleanup
- * - now is possible to redefine texture mipmap levels already defined

- * with not all mipmap levels defined
- * - fixed a small problem with single buffer rendering
- *

+ * Version: 3.3
*
- * V0.18 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.

- * - performance improvement setting VBSIZE to 72
- * - the GrVertex texture code is now written in asm
- * - the GrVertex zbuffer code is now written in asm
- * - the GrVertex wbuffer code is now written in asm
- * - the GrVertex gouraud code is now written in asm
- * - the GrVertex snap code is now written in asm
- * - changed the 8bit compressed texture maps in 8bit palette texture maps
- * support (it has the some advantage of compressed texture maps without the
- * problem of a fixed NCC table for all mipmap levels)
- * - written the support for 8bit compressed texture maps (but texture maps with
- * more than one mipmap level aren't working fine)
- * - finnaly everthing is working fine in MesaQuake !

- * - tested with the Hercules Stingray 128/3D (The rendering in a window works !)
- *
- * V0.15 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
- * - written the GL_LUMINANCE_ALPHA support
- * - written the GL_ALPHA support
- * - written the GL_LUMINANCE support
- * - now SETUP correctly set color for mono color sequences
- * - written the 9x1,10x1,...,1x9,1x10,... texture map ratio support
- * - written the no square texture map support
- * - the fog table is no more rebuilt inside setup_fx_units() each time
- *
- * Henri Fousse (arnaud@pobox.oleane.com) Thomson Training & Simulation
- * - written (not yet finished: no texture mapping) support for glOrtho
- * - some change to setup functions
- * - the fog support is now fully compatible with the standard OpenGL
- * - rewritten several parts of the driver in order to take
- * advantage of meshes (40% faster !!!)
- *
- * V0.14 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
- * - now glAlphaFunc() works
- * - now glDepthMask() works
- * - solved a mipmap problem when using more than one texture
- * - moved ti, texid and wscale inside the fxMesaContext (now we can
- * easy support more ctx and more boards)
- * - the management of the fxMesaContext was completly broken !
- * - solved several problems about Alpha and texture Alpha
- * - 4 (RGBA) texture channels supported
- * - setting the default color to white
- *
- * Henri Fousse (arnaud@pobox.oleane.com) Thomson Training & Simulation
- * - small change to fxMesaCreateContext() and fxMesaMakeCurrent()
- * - written the fog support
- * - setting the default clear color to black
- * - written cleangraphics() for the onexit() function
- * - written fxMesaCreateBestContext()
- *
- * V0.13 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
- * - now glBlendFunc() works for all glBlendFunc without DST_ALPHA
- * (because the alpha buffer is not yet implemented)
- * - now fxMesaCreateContext() accept resolution and refresh rate
- * - fixed a bug for texture mapping: the w (alias z) must be set
- * also without depth buffer
- * - fixed a bug for texture image with width!=256
- * - written texparam()
- * - written all point, line and triangle functions for all possible supported
- * contexts and the driver is slight faster with points, lines and small triangles
- * - fixed a small bug in fx/fxmesa.h (glOrtho)
- *
- * V0.12 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
- * - glDepthFunc supported
- * - introduced a trick to discover the far plane distance
- * (see fxMesaSetFar and fx/fxmesa.h)
- * - now the wbuffer works with homogeneous coordinate (and it
- * doesn't work with a glOrtho projection :)
- * - solved several problems with homogeneous coordinate and texture mapping
- * - fixed a bug in all line functions
- * - fixed a clear framebuffer bug
- * - solved a display list/teximg problem (but use
- * glBindTexture: it is several times faster)
- *
- * V0.11 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
- * - introduced texture mapping support (not yet finished !)
- * - tested with Mesa2.2b6
- * - the driver is faster
- * - written glFlush/glFinish
- * - the driver print a lot of info about the Glide lib
- *
- * v0.1 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
- * - Initial revision
+ * Additional Mesa/3Dfx driver developers:
+ * Daryll Strauss <daryll@precisioninsight.com>
