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