* Remove clamp parameter from _mesa_unpack_color_span_float(). Pass theBrian Paul2004-02-282-47/+53
| | | | | | IMAGE_CLAMP_BIT if needed. Added ClampVertexColors and ClampFragmentColors to GLcontext in anticipation of upcoming extensions (not fully used yet).

* A few more tweaks to fog code.Brian Paul2004-02-171-4/+8
| | | | | Remove unneeded FABSF() macros. Added blend factor clamping in a few spots.
* A bit of an overhaul of the fog code.Brian Paul2004-02-176-199/+262
| | | | | | glFogCoord didn't always work reliably. ARB fragment program fog options work now. Per-fragment fog computations are now perspective corrected.
* added SPAN_WBrian Paul2004-02-171-8/+9

* just some reformattingBrian Paul2004-02-171-16/+17

|
* Minor clean-ups of variable scopes, initializations, etc.Brian Paul2004-02-151-29/+51
| | | | | New comments discussing FIXED_FRAC_BITS, SUB_PIXEL_BITS, max viewport size and rasterization accuracy.

* Added support for EXT_blend_equation_separate / ATI_blend_equation_separate.Ian Romanick2004-01-271-25/+93
| | | | | The internal driver interface was also changed to use BlendEquationSeparate instead of BlendEquation.

| | | | casts.
* Initial support for floating point and signed texture formats.Brian Paul2004-01-232-35/+36
| | | | | | | New "FetchTexelFuncF()" function returns texels in floating point format. Only used for depth component images at this time. Changed original FetchTexelFunc to return GLchan instead of GLvoid, removing need for a bunch of ugly casts.

* More SciTech SNAP updates. Some of these files didn't really change, butKendall Bennett2003-10-222-6/+1
| | | | | | | they show up in the list (GLU stuff) for some reason. The major change here is the addition of code in the glx86asm.py file to generate assembler stub entry points with the correct name decorations for _stdcall calling conventions so this can be used on Windows boxes.
