C# Класс Axiom.Graphics.UnifiedHighLevelGpuProgram

Whilst you can use Technique to implement several ways to render an object depending on hardware support, if the only reason to need multiple paths is because of the high-level shader language supported, this can be cumbersome. For example you might want to implement the same shader in HLSL and GLSL for portability but apart from the implementation detail, the shaders do the same thing and take the same parameters. If the materials in question are complex, duplicating the techniques just to switch language is not optimal, so instead you can define high-level programs with a syntax of 'unified', and list the actual implementations in order of preference via repeated use of the 'delegate' parameter, which just points at another program name. The first one which has a supported syntax will be used.
