2008-12-10gallium: added draw_set_mrd() function to fix polygon offsetBrian Paul
The Minimum Resolvable Depth factor depends on the driver and can't just be computed from the number of Z buffer bits. Glean's polygon offset test now passes with softpipe. Still need to determine the MRD factor for other gallium drivers, if they use the draw module's polygon offset stage...

2008-12-04gallium: added draw_texture_samplers() to support texture fetches from ↵Brian
vertex shaders This may only be practical for the softpipe driver at this time.
2008-10-07draw: add switch for drivers to force vertex data passthroughKeith Whitwell
2008-08-25gallium: added const qualifiers on some draw funcsBrian
2008-05-29draw: make sure constant buffer data is aligned before passing to aos.cKeith Whitwell
2008-05-29draw: draw_range_elements trialKeith Whitwell
2008-04-22draw: allow drivers to query pipeline state more easilyKeith Whitwell
Also, provide a separate flag to say whether the driver can handle clipping/rhw tasks, in addition to the API flag which indicates they have already been done.
2008-04-21draw: propogate lots of errorsKeith Whitwell
2008-04-21draw: propogate errors out of aapoint stageKeith Whitwell

2008-04-21gallium: Centralize SSE usage logic.José Fonseca
2008-04-19draw: remove named clipmask flags, tidy up pt middle endsKeith Whitwell
2008-04-04gallium: Handle client-supplied edgeflags.Keith Whitwell
Also, implement support in the draw module. We were hardwiring these to one for quite a long time... Currently using a draw_set_edgeflags() function, may be better to push the argument into the draw_arrays() function. TBD.
2008-03-29gallium: Set vertex state/buffers en-mass.Brian Paul
2008-03-14gallium: add explicit control for point sprites (convert points to textured ↵Brian
quads) New draw_enable_point_sprites() function. Fixes spriteblast.c demo
2008-03-13gallium: added draw_enable_line_stipple() functionBrian
Allows drivers that implement line stipple to turn off this drawing stage.
2008-03-10draw: placeholder/prototype code for a passthrough draw pathKeith Whitwell
2008-02-28gallium: split draw_wide_prim stage into separate point/line stages.Brian Paul
This fixes a validation/code-path problem. Enabling the stage for the sake of wide points also inadvertantly caused wide lines to be converted to tris when we actually want them passed through, such as for the AA line stage. This is just cleaner now. Also, replace draw_convert_wide_lines() with draw_wide_line_threshold() as was done for points. Allows for 1-pixel lines to be converted too if needed.
2008-02-27gallium: added draw_num_vs_outputs() to query number of post-transform ↵Brian
vertex attribs
2008-02-26gallium: updated prototype (missed in prev commit)Brian
2008-02-21gallium: new draw stage for polygon stipple.Brian
For hardware without native polygon stipple. Create a 32x32 alpha texture that encodes the stipple pattern. Modify the user's fragment program to sample the texture (with gl_FragCoord) and kill the fragment according to the texel value. Temporarily enabled in softpipe driver, replacing the sp_quad_stipple.c step.
2008-02-21gallium: new AA point drawing stageBrian
AA points are drawn by converting the point to a quad, then modifying the user's fragment shader to compute a coverage value. The final fragment color's alpha is modulated by the coverage value. Fragments outside the point's radius are killed.
2008-02-18gallium: antialiased line drawingBrian
New draw/prim stage: draw_aaline. When installed, lines are replaced by textured quads to do antialiasing. The current user-defined fragment shader is modified to do a texture fetch and modulate fragment alpha.
