Function CompileShader

shadercompiler/ShaderCompiler.cpp:116–191

-------------------------------------------------------------------------------------- Description: Worker thread for compiling shader permutations. Fetches next permutation from input queue, compiles it and puts result into g_compiledEffects. Arguments: param - unused Return value: 0 always --------------------------------------------------------------------------------------
