+ Sampler arrays can take a variable index now, as long as it's value is uniform for all uses.
- 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.)

- Add gl_FragDepth layout qualifiers to communicate what kind of changes will be made to gl_FragDepth (GL_AMD_conservative depth).
+ Add C-style curly brace initializer lists syntax for initializers. Full initialization of aggregates is required when these are used.
+ Allow .length() to be applied to vectors and matrices, returning the number of components or columns.
