This is a partial implemention of structurebuffers supporting: * structured buffer types of: * StructuredBuffer * RWStructuredBuffer * ByteAddressBuffer * RWByteAddressBuffer * Atomic operations on RWByteAddressBuffer * Load/Load[234], Store/Store[234], GetDimensions methods (where allowed by type) * globallycoherent flag But NOT yet supporting: * AppendStructuredBuffer / ConsumeStructuredBuffer types * IncrementCounter/DecrementCounter methods Please note: the stride returned by GetDimensions is as calculated by glslang for std430, and may not match other environments in all cases.
