2010-06-10swrast: When reading from a 0-bits r,g,b channel, return 0 not 1.Eric Anholt
It looks like we were reading a fractional value, multiplying by an enormous negative value, then stuffing that value into a bitfield assuming it was already clamped. This becomes relevant for GL_ALPHA or R/RG FBOs.

2010-03-23swrast: improve depth texture mipmap selectionBrian Paul
We still don't do proper min/mag filtering but this is better than just sampling the base mipmap level all the time. Fixes piglit depth-level-clamp test. Fixes fd.o bug 27256.

2010-03-05swrast: Remove redundant test of the visual's accumulation buffer sizeIan Romanick
If the visual doesn't have an accumulation buffer, the renderbuffer passed into _swrast_clear_accum_buffer will be NULL anyway. There is no reason the check the visual. Moreover, the test erroneously checks the context's visual instead of the visual of the current DrawBuffer. With FBOs these may be different. Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>
2010-03-05swrast: Adjust colors based on ReadBuffer visual, not context visualIan Romanick
In the presence of FBOs, the visual of the context may not match the, possibly fake, visual of the current ReadBuffer. Note that the caller of adjust_colors correctly uses the visual of the ReadBuffer. Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>

2010-01-26swrast: Implement ARB_fragment_coord_conventions but don't enable.Eric Anholt
This brings swrast's support up to the state of gallium, and fixes the default center behavior of fragment.position.xy in piglit fp-arb-fragment-coord-conventions-none. The extension is not enabled currently because the GLSL part of the extension isn't supported, so piglit glsl-arb-fragment-coord-conventions-define fails as would any serious test of the GLSL part.

2010-01-15swrast: add missing call to _swrast_depth_bounds_test()Brian Paul
We were calling this from the CI span function, but not the RGBA span function. I don't know of a test program for the GL_EXT_depth_bounds_test extension...
2010-01-15swrast: fix broken _swrast_depth_clamp_span()Brian Paul
The integer Z clamping range depends on the number of bits in the Z buffer because that's the scale factor used when we transform NDC coords by the viewport/depth range. Fixes fd.o bug #25972 but only for Z buffers up to a depth of 30 bits. Beyond that we get into messy integer overflow issues and things fall apart.
