Detailed Description

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. Therefore the GLSLShader will also stand in 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 the GLSLProgramManager to request a program object to link the shader object to.

Note: 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 separated by white space.
