SHADERINFO_0	None.
SHADERINFO_TRANSFORM	Channel needs back-transformed data. (Required for back_p.)
SHADERINFO_BUMP_SUPPORT	Channel shader supports the new bump system. This is strongly recommended for all shaders but simple 2D (UV) samplers.
SHADERINFO_ALPHA_SUPPORT	Channel shader supports alpha output.
SHADERINFO_REFLECTIONS	Channel shader computes reflections.
SHADERINFO_DUDVREQUIRED	Channel shader needs du/dv bump mapping data.
SHADERINFO_DYNAMICSUBSHADERS	Channel shader has a dynamic list of subshaders in its description.
