Static Samplers

samplers definitions. However, the definition is a fixed sized struct,
containing 13 32-byte fields of various enum, float, and integer values.

In version 1.2, the static sampler is 17 bytes. It matches the 1.0 static sampler
but adds a 32-bit access flag. In Version 1.1, it matches static sampler
version 1.0.
