Detailed Description

A shader represents an entire shader resource, containing several stages and programs.

ShaderId - A shader resource handle. It cannot be used for anything other than quering the shader file (usually suffixed with .fx) for reflection information.

ShaderStateId - An instantiation of either all or a subset of the variables in that shader. The state contains the, well, state of all resources (constant buffers, textures, read/write buffers) as well as the constant values.

ShaderProgramId - The shader will most likely have a set of shader permutations, and those permutations are called programs. The ShaderProgramId binds both the shader, and an associated permutation in one call.

ShaderConstantId - The resources applied with the ShaderStateId are more atomically defined as constants, and serves both as individual shader constants (variables in CPU time, constant in GPU time) as well as the resource binds to that state. They are bound to a inherently bound to a state, and such modifying a constant requires both the state and constant id for that state.
