The problem was that the shader constants were based on the framebuffer sample count and ignored the multisample enable state and the line/polygon smoothing state, which uses MSAA rasterization that only sets SampleMaskIn to get the coverage for alpha-blended smoothing (the PS epilog computes the alpha channel from SampleMaskIn and blending generates the AA results). - This is a complete rework that adds a new state for NGG cull constants. - It fixes the same thing for the prim discard compute shader. - It documents how VS_STATE.SMALL_PRIM_PRECISION is encoded. It fixes blue corruption in Unigine Heaven with MSAA and Medium details or better.
