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 ([email protected]) Avid Technology - * - added write_monocolor_span(), fixed bug in write_color_span() - * - added test for stenciling in choosepoint/line/triangle functions - * - * Joe Waters ([email protected]) Aegis - * - written the support for the env. var.

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 - * - fixed a problem with the amount of texture memory allocated for textures - * with not all mipmap levels defined - * - fixed a small problem with single buffer rendering - * - * Brian Paul ([email protected]) Avid Technology - * - read/write_color_span() now use front/back buffer correctly - * - create GLvisual with 5,6,5 bits per pixel, not 8,8,8 - * - removed a few ^M characters from fxmesa2.c file - * - * V0.18 - David Bucciarelli ([email protected]) Humanware s.r.l. - * - the Mesa-2.4beta3 is finally using the driver quads support (the - * previous Mesa versions have never taken any advantage from the quads support !) - * - tested with the Glide 2.4 for Win - * - ported all asm code to Linux - * - ported the v0.18 to Linux (without asm code) - * - back to Linux !!! - * - optimized the SETUP macro (no more vertex snap for points and lines) - * - optimized the SETUP macro (added one argument) - * - the Mesa/Voodoo is now 20/30% for points, lines and small triangles ! - * - 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 ! - * - fixed a bug in the computation of texture mapping coordinates (I have found - * the bug thanks to MesaQuake !) - * - written the GL_REPLACE support (mainly for MesaQuake) - * - written the support for textures with not all mipmap levels defined - * - rewritten all the Texture memory stuff - * - written the MesaQuake support (define MESAQUAKE) - * - working with a ZBuffer if glOrtho or not int the default glDepthRange, - * otherwise working with the WBuffer - * written the glDepthRange support - * - * Diego Picciani ([email protected]) Nova Computer s.r.l. - * - written the fxCloseHardware() and the fxQuaryHardware() (mainly - * for the VoodooWGL emulator) - * - * Brian Paul ([email protected]) Avid Technology - * - implemented read/write_color_span() so glRead/DrawPixels() works - * - now needs Glide 2.3 or later.
