[Mesa-dev] [PATCH 0/4] Removal of point size clamping in st/mesa

[Marek Olšák]

Hi everyone,

the subject says it all. This series fixes gl_PointSize with transform feedback. There is a new piglit test to verify that a driver does clamping properly during rasterization: vs-point_size-zero

I haven't changed Draw, because softpipe and llvmpipe do the clamping internally somewhere. (I didn't take a look where they do it, but they pass the test, which can't be said about r600 with point size clamping disabled)

The only drivers I am not sure about are i915 and nouveau.

Please review.

Marek
