GLSL Mirroring

TextureSamplers correspond to the following GLSL samplers, when you see a g preceding a sampler name, it represents any of the 3 possible prefixes (nothing for float, i for signed integer, and u for unsigned integer):

Texture Kind | GLSL sampler -------------|------------- D1 | gsampler1D, sampler1DShadow D1Array | gsampler1DArray, sampler1DArrayShadow D2 | gsampler2D, gsampler2DMS, sampler2DShadow D2Array | gsampler2DArray, gsampler2DMSArray, sampler2DArrayShadow D3 | gsampler3D Cube | gsamplerCube, samplerCubeShadow CubeArray | gsamplerCubeArray, samplerCubeArrayShadow

Buffer resource views are seen as gsamplerBuffer.

Rust basic type | GLSL (1.3 and above) ----------------|--------------------- i32 | int u32 | uint f32 | float f64 | double
