- * It works fine
- * - written the support for standard OpenGL antialiasing using
- * blending. Lines support works fine (tested with BZflag)
- * while I have still to check the polygons and points support
- * - written the support for the alpha buffer. The driver is now
- * able to use the Voodoo auxiliary buffer as an alpha buffer

- * - written the support for the MESA_WGL_FX env. var. but
- * not tested because I have only Voodoo Graphics boards
- * - fixed a bug in the backface culling code
- * (thanks to David Farrell for an example of the problem)
- * - fixed the "Quake2 elevator" bug
- * - GL_POLYGONS with 3/4 vertices are now drawn as
- * GL_TRIANLGES/GL_QUADS (a small optimization for GLQuake)
- * - fixed a bug in fxmesa6.h for GL_LINE_LOOP
- * - fixed a NearFarStack bug in the Mesa when applications
- * directly call glLoadMatrix to load a projection matrix
- * - done some cleanup in the fxmesa2.c file
- * - the driver no longer translates the texture maps
- * when the Mesa internal format and the Voodoo
- * format are the some (usefull for 1 byte texture maps
- * where the driver can directly use the Mesa texture
- * map). Also the amount of used memory is halfed
- * - fixed a bug for GL_DECAL and GL_RGBA
- * - fixed a bug in the clear_color_depth()
- * - tested the v0.22 with the Mesa-2.6beta2. Impressive
- * performances improvement thanks to the new Josh's
- * asm code (+10fps in the isosurf demo, +5fps in GLQuake
- * TIMEREFRESH)
- * - written a optimized version of the RenderVB Mesa driver
- * function. The Voodoo driver is now able to upload polygons
- * in the most common cases at a very good speed. Good
- * performance improvement for large set of small polygons

- * in the Glide grVertex structure
- * - fixed a bug in the fxmesa2.c asm code (the ClipMask[]
- * wasn't working)
- *
- * Josh Vanderhoof (joshv@planet.net)
- * - removed the flush() function because it isn't required
- * - limited the maximum number of swapbuffers in the Voodoo
- * commands FIFO (controlled by the env. var. MESA_FX_SWAP_PENDING)
- *
- * Holger Kleemiss (holger.kleemiss@metronet.de) STN Atlas Elektronik GmbH
- * - applied some patch for the Voodoo Rush
- *
- * V0.21 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
- * - 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
- * mapping support is compliant to the OpenGL specs (GL_BLEND
- * 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()
- * - added test for stenciling in choosepoint/line/triangle functions
- *
- * Joe Waters (falc@attila.aegistech.com) Aegis
- * - written the support for the env. var. SST_SCREENREFRESH
- *
- * V0.19 - David Bucciarelli (tech.hmw@plus.it) Humanware s.r.l.
- * - 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
- * - 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 (brianp@elastic.avid.com) 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 (tech.hmw@plus.it) 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 (d.picciani@novacomp.it) Nova Computer s.r.l.
- * - written the fxCloseHardware() and the fxQuaryHardware() (mainly
- * for the VoodooWGL emulator)
- *
- * Brian Paul (brianp@elastic.avid.com) Avid Technology
- * - implemented read/write_color_span() so glRead/DrawPixels() works
- * - now needs Glide 2.3 or later. Removed GLIDE_FULL_SCREEN and call to grSstOpen()

- * - linux stuff
- * - general code clean-up

- * Horner scheme for Bezier curves

- * Since stability is not important for displaying curve
- * points I decided to use the Horner scheme.

- * Arbitrary axis rotation matrix.
- *
- * This is composed of 5 matrices, Rz, Ry, T, Ry', Rz', multiplied
- * like so: Rz * Ry * T * Ry' * Rz'. T is the final rotation
- * (which is about the X-axis), and the two composite transforms
- * Ry' * Rz' and Rz * Ry are (respectively) the rotations necessary
- * from the arbitrary axis to the X-axis then back. They are
- * all elementary rotations.
- *
- * Rz' is a rotation about the Z-axis, to bring the axis vector
- * into the x-z plane. Then Ry' is applied, rotating about the
- * Y-axis to bring the axis vector parallel with the X-axis. The
- * rotation about the X-axis is then performed. Ry and Rz are
- * simply the respective inverse transforms to bring the arbitrary
- * axis back to it's original orientation. The first transforms
- * Rz' and Ry' are considered inverses, since the data from the
- * arbitrary axis gives you info on how to get to it, not how
- * to get away from it, and an inverse must be applied.
- *
- * The basic calculation used is to recognize that the arbitrary
- * axis vector (x, y, z), since it is of unit length, actually
- * represents the sines and cosines of the angles to rotate the
- * X-axis to the same orientation, with theta being the angle about
- * Z and phi the angle about Y (in the order described above)
- * as follows:
- *
- * cos ( theta ) = x / sqrt ( 1 - z^2 )
- * sin ( theta ) = y / sqrt ( 1 - z^2 )
- *
- * cos ( phi ) = sqrt ( 1 - z^2 )
- * sin ( phi ) = z
- *
- * Note that cos ( phi ) can further be inserted to the above
- * formulas:
- *
- * cos ( theta ) = x / cos ( phi )
- * sin ( theta ) = y / sin ( phi )
- *
- * ...etc. Because of those relations and the standard trigonometric
- * relations, it is pssible to reduce the transforms down to what
- * is used below. It may be that any primary axis chosen will give the
- * same results (modulo a sign convention) using thie method.
- *
- * Particularly nice is to notice that all divisions that might
- * have caused trouble when parallel to certain planes or
- * axis go away with care paid to reducing the expressions.
- * After checking, it does perform correctly under all cases, since
- * in all the cases of division where the denominator would have
- * been zero, the numerator would have been zero as well, giving
- * the expected result.

+ * Arbitrary axis rotation matrix.
+ *
+ * This is composed of 5 matrices, Rz, Ry, T, Ry', Rz', multiplied
+ * like so: Rz * Ry * T * Ry' * Rz'. T is the final rotation
+ * (which is about the X-axis), and the two composite transforms
+ * Ry' * Rz' and Rz * Ry are (respectively) the rotations necessary
+ * from the arbitrary axis to the X-axis then back. They are
+ * all elementary rotations.
+ *
+ * Rz' is a rotation about the Z-axis, to bring the axis vector
+ * into the x-z plane. Then Ry' is applied, rotating about the
+ * Y-axis to bring the axis vector parallel with the X-axis. The
+ * rotation about the X-axis is then performed. Ry and Rz are
+ * simply the respective inverse transforms to bring the arbitrary
+ * axis back to it's original orientation. The first transforms
+ * Rz' and Ry' are considered inverses, since the data from the
+ * arbitrary axis gives you info on how to get to it, not how
+ * to get away from it, and an inverse must be applied.
+ *
+ * The basic calculation used is to recognize that the arbitrary
+ * axis vector (x, y, z), since it is of unit length, actually
+ * represents the sines and cosines of the angles to rotate the
+ * X-axis to the same orientation, with theta being the angle about
+ * Z and phi the angle about Y (in the order described above)
+ * as follows:
+ *
+ * cos ( theta ) = x / sqrt ( 1 - z^2 )
+ * sin ( theta ) = y / sqrt ( 1 - z^2 )
+ *
+ * cos ( phi ) = sqrt ( 1 - z^2 )
+ * sin ( phi ) = z
+ *
+ * Note that cos ( phi ) can further be inserted to the above
+ * formulas:
+ *
+ * cos ( theta ) = x / cos ( phi )
+ * sin ( theta ) = y / sin ( phi )
+ *
+ * ...etc. Because of those relations and the standard trigonometric
+ * relations, it is pssible to reduce the transforms down to what
+ * is used below. It may be that any primary axis chosen will give the
+ * same results (modulo a sign convention) using thie method.
+ *
+ * Particularly nice is to notice that all divisions that might
+ * have caused trouble when parallel to certain planes or
+ * axis go away with care paid to reducing the expressions.
+ * After checking, it does perform correctly under all cases, since
+ * in all the cases of division where the denominator would have
+ * been zero, the numerator would have been zero as well, giving
+ * the expected result.

+ *
+ * Clipping is a convenient place to do the divide on x86 as it should be

+ *
+ * There are two cases where we wouldn't want to do the divide in cliptest:
+ * - When we aren't clipping. We still might want to cull backfaces
+ * so the divide should be done elsewhere. This currently never
+ * happens.
+ *
+ * - When culling isn't likely to help us, such as when the GL culling
+ * is disabled and we not lighting or are only lighting
+ * one-sided. In this situation, backface determination provides
+ * us with no useful information. A tricky case to detect is when
+ * all input data is already culled, although hopefully the
+ * application wouldn't turn on culling in such cases.
+ *
+ * We supply a buffer to hold the [x/w,y/w,z/w,1/w] values which
+ * are the result of the projection. This is only used in the
+ * 4-vector case - in other cases, we just use the clip coordinates
+ * as the projected coordinates - they are identical.
