Detailed Description

Specialisation of HighLevelGpuProgram to provide support for Metal Shader Language.

Remarks: Metal 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. Metal also does not provide assembler low level output after compiling. The Metal Render system assumes that the Gpu program is a Metal Gpu program so MetalProgram will create a MetalGpuProgram that is subclassed from MetalGpuProgram for the low level implementation. The MetalProgram class will create a shader object and compile the source but will not create a program object. It's up to MetalGpuProgram class to request a program object to link the shader object to.
