Shader Library

Simple include system for glsl files.

Usage: Create a DRWShaderLibrary and add the library in the right order. You can have nested dependencies but each new library needs to have all its dependencies already added to the DRWShaderLibrary. Finally you can use DRW_shader_library_create_shader_string to get a shader string that also contains the needed libraries for this shader.
