2010-01-15	llvmpipe: generate two shader varients, one omits triangle in/out testing	Brian Paul
	When we know that a 4x4 pixel block is entirely inside of a triangle use the jit function which omits the in/out test code. Results in a few percent speedup in many tests.
2009-12-17	llvmpipe: replace INT_MIN/2 with INT_MIN	Brian Paul
	Since changing the in/out test we can just use INT_MIN to be sure the comparison against the step values always passes.
2009-12-17	llvmpipe: improve the in/out test a little	Brian Paul
	Instead of: s = c + step m = s > 0 Do: m = step > c (with negated c)
2009-12-16	llvmpipe: do final the pixel in/out triangle test in the fragment shader	Brian Paul
	The test to determine which of the pixels in a 2x2 quad is now done in the fragment shader rather than in the calling C code. This is a little faster but there's a few more things to do. Note that the step[] array elements are in a different order now. Rather than being in row-major order for the 4x4 grid, they're in "quad-major" order. The setup of the step arrays is a little more complicated now. So is the course/intermediate tile test code, but some lookup tables help with that. Next steps: - early-cull 2x2 quads which are totally outside the triangle. - skip the in/out test for fully contained quads - make the in/out comparison code tighter/faster.
2009-12-07	llvmpipe: repartition lp_rasterizer state for threading	Brian Paul
	Some of the state is per-thread. Put that state in new lp_rasterizer_task struct.
2009-12-04	llvmpipe: use LP_DBG() macro everywhere	Brian Paul

2009-12-01	llvmpipe: added assertions	Brian Paul
	And remove unused BLOCKSIZE.
2009-12-01	llvmpipe: simplify mask computation	Brian Paul
	Make this a little easier to understand.
2009-12-01	llvmpipe: replace shifts with multiplies to be clearer	Brian Paul
	The compiler will still do the multiplies with shifts. It's just a bit easier to follow the logic with multiplies.
2009-12-01	llvmpipe: make nr_blocks unsigned	Brian Paul

2009-12-01	llvmpipe: comments, reformatting and assertions in tri rast code	Brian Paul

2009-10-20	llvmpipe: move block list into rast struct	Keith Whitwell

2009-10-20	llvmpipe: recursive rasterization within a tile	Keith Whitwell

2009-10-20	llvmpipe: precalculate some offsets	Keith Whitwell

2009-10-19	llvmpipe: calculate masks in format desired by shader	Keith Whitwell
	Also remove branches calculating masks for quads.
2009-10-19	llvmpipe: pre-multiply some constants by fixed_one	Keith Whitwell

2009-10-19	llvmpipe: Reshape the shader input from 8x2 to 4x4.	José Fonseca
	Incorrect rendering until the interpolation code generation is updated.
2009-10-19	llvmpipe: fixed-point rasterization	Keith Whitwell

2009-10-10	llvmpipe: Only invoke the shader if necessary.	José Fonseca

2009-10-09	llvmpipe: Fix type in tri bounding box check.	José Fonseca

2009-10-09	llvmpipe: just bin whole tiles for now	Keith Whitwell

2009-10-09	llvmpipe: get lp_setup_tri building	Keith Whitwell

2009-10-09	llvmpipe: use union lp_cmd_rast_arg directly, rather than through a pointer	Keith Whitwell
	The union itself consists of pointers. We don't need to be passing pointer to pointers.
