C# Class Axiom.RenderSystems.OpenGL.GLSL.GLSLProgram

Specialisation of HighLevelGpuProgram to provide support for OpenGL Shader Language (GLSL).
GLSL has no target assembler or entry point specification like DirectX 9 HLSL. Vertex and Fragment shaders only have one entry point called "main". When a shader is compiled, microcode is generated but can not be accessed by the application. GLSL also does not provide assembler low level output after compiling. The GL Render system assumes that the Gpu program is a GL Gpu program so GLSLProgram will create a GLSLGpuProgram that is subclassed from GLGpuProgram for the low level implementation. The GLSLProgram class will create a shader object and compile the source but will not create a program object. It's up to GLSLGpuProgram class to request a program object to link the shader object to.

GLSL supports multiple modular shader objects that can be attached to one program object to form a single shader. This is supported through the "attach" material script command. All the modules to be attached are listed on the same line as the attach command seperated by white space.
