Detailed Description A shader object loads itself from a shader resource file, and contains everything to render a mesh and texture. It may be completely render state based, use vertex and pixel shader programs, or both. Shaders usually use a 3rd party subsystem, like D3DX effects, or CgFX. This is done by subclasses of the nShader2 class. How the shader is rendered is totally up to the gfx server. For the sake of efficiency, shader parameters are now enums with associated string names. The use of enums allows to do parameter lookup as simple indexed array lookup. The disadvantage is of course, that new shader states require this file to be extended or replaced.
