- Per-sample shading. Including sample input mask gl_SampleMaskIn[] and per-sample interpolation, with explicit interpolation built-ins interpolateAtCentroid(), interpolateAtSample(), and interpolateAtOffset().
- New precise qualifier to disallow optimizations that re-order operations or treat different instances of the same operator with different precision.
- Add a fused multiply and add built-in, fma(), in relation to the new precise qualifier. (Because <20>a * b + c<> will require two operations under new rules for precise.)
