2007-09-27mesa: make sure the gotten value isn't greater than theXiang, Haihao
max depth buffer value on 64bit system. fix bug #12095
2007-08-16remove reference to ctx->Color.DrawBufferBrian
2007-07-26fix color interpolation for CHAN_BITS==32Brian
2007-06-29Undo some prev glDraw/CopyPixel changes which fixed a bug in which colors ↵Brian
were overwritten by interpolating attributes. Now just set the span->arrayAttribs mask in glDraw/CopyPixels and be sure we don't overwrite the values in interpolate_active_attribs().
2007-06-22fix bug rendering points with fragment program (see #11330)Brian
2007-06-21fix rgba pointer bug hit on zoomed+fogged glDrawPixelsBrian
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.
2007-06-20fix glDrawPixels + fragment program problemBrian
2007-05-20Overhaul/simplify SWvertex and SWspan attribute handling.Brian
Instead of separate fog/specular/texcoord/varying code, just treat all of them as generic attributes. Simplifies the point/line/triangle functions.
2007-05-02changes to get DDX/DDY working againBrian
2007-04-21Fix color sum bug 10688.Brian
2007-04-19Don't allow deferredTexture if using occlusion query and a frag shader.Brian
Occlusion query might depend on the shader killing/discarding fragments. Helps fix depth peeling technique. Also, minor tweaks in interpolate_wpos().
2007-04-18check _PreferPixelFog in _swrast_span_default_fog(), see bug 10669Brian
2007-04-07fix comment typoBrian
2007-03-26Add _swrast_span_default_secondary_color() for use with glBitmap, ↵Brian
glDrawPixels, etc. Secondary color wasn't getting added to post-texture color when drawing bitmaps, images. See bug 10409.

progs
2007-03-11Implement support for GL_ARB_draw_buffers with GL_MAX_DRAW_BUFFERS > 1.Brian
GL_MAX_DRAW_BUFFERS is currently 4. Added gl_FragData[] output for fragment programs. In _swrast_write_rgba_span() loop over the color outputs/renderbuffers.

2007-02-02Replace color, z, w, texture interpolants with new generic attrib interpolants.Brian
2007-02-02New span attrStart/attrStepX/attrStepY fields to replace fog, specular, etc. ↵Brian
fields. More to come.

2007-02-01New SWspanarrays attribs[] array.Brian
Replace texcoord[], varying[], etc. arrays with single attribs[] array, indexed by FRAG_ATTRIB_* values. Eliminates need to copy data into fragment program machine input registers. Will lead to future clean-ups.

2006-10-12Lots of changes to support runtime renderbuffer depths.Brian Paul
_swrast_read_rgba_span() now takes a datatype parameter. New optimization for glReadPixels(format=GL_RGB). New glCopyPixels optimization for the simple, common cases.
