[Mesa-dev] [RFC] llvmpipe texture coordinate rounding

In doing some testing we’ve noticed that trying to draw pixel aligned textures does not work very well with linear filtering in llvmpipe.Here’s an example of the problem.Imagine wanting to paint a 100x100 texture. After being scaled by 100 the texture coordinates will end up as:0.5, 1.5, 2.5, 3.5,
