First special instruction Start Load/Store implementation Start TextureSample Sample progress I/O Load/Store Progress Rest of load/store TODO: Currently, the generator still assumes the GLSL style of I/O attributres. On MSL, the vertex function should output a struct which contains a float4 with the required position attribute. TextureSize and VectorExtract Fix UserDefined IO Vars Fix stage input struct names
