2008-01-06Simplify ctx->_NumColorDrawBuffers, _ColorDrawBuffers and fix bug 13835.Brian
These fields are no longer indexed by shader output. Now, we just have a simple array of renderbuffer pointers. If the shader writes to gl_FragData[i], send those colors to the N _ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or the fixed-function color) to the N _ColorDrawBuffers. A few more changes and simplifications can follow from this...

2007-10-29Rename 'mms-config.' to 'mms.config'.Michal Krol
It looks like Windows does not like filenames ending with a dot, in effect renaming it to 'mms-config'.
2007-10-26Re-implement GLSL texture sampler variables.Brian
GLSL sampler variables indicate which texture unit to use for TEX instructions. Previously, this was baked into the fragment/vertex program and couldn't be readily changed once set. Now, SamplerUnits[] array indicates which texture unit is to be used for each sampler variable. These values are set with glUniform1i(). This is extra state that must be passed to the fragment/vertex program executor at runtime.

2007-07-21Remove ctx->Point._Size and ctx->Line._Width.Brian
The clamping for these values depends on whether we're drawing AA or non-AA points, lines. Defer clamping until drawing time. Drivers could compute and keep clamped AA and clamped non-AA values if desired.

2007-06-21Another round of fixing attribute interpolation for glDraw/CopyPixels.Brian
Need to turn off FRAG_BIT_COL0 in swrast->_ActiveAttribMask when doing glRead/CopyPixels to prevent the user's colors from getting overwritten when a fragment program is active. This was happening in the DRI drivers when MaintainTexEnv program was used (the texenv fragment program was enabled when _swrast_DrawPixels was called). This still isn't an ideal solution, but fixes things for now.
