C# Class Axiom.CgPrograms.CgProgram

Specialization of HighLevelGpuProgram to provide support for nVidia's Cg language.
Cg can be used to compile common, high-level, C-like code down to assembler language for both GL and Direct3D, for multiple graphics cards. You must supply a list of profiles which your program must support using SetProfiles() before the program is loaded in order for this to work. The program will then negotiate with the renderer to compile the appropriate program for the API and graphics card capabilities.
