## Detailed Description

Specialisation of HighLevelGpuProgram to provide support for OpenGL Shader Language (GLSL ES) for OpenGL ES 2.0.

Remarks
  GLSL ES 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 ES also does not provide assembler low level output after compiling. The GL ES Render system assumes that the Gpu program is a GL Gpu program so GLSLESProgramPipeline will create a GLSLESGpuProgram that is subclassed from GLES2GpuProgram for the low level implementation. The GLES2Program class will create a shader and program object and compile the source but will not create a pipeline object. It's up to GLES2GpuProgram class to request a program pipeline object to link the program object to.

Note
  GLSL ES 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.
