Refactored graph: Reduce/remove data copy/recreation; Shader cleanup
- Pass the current GL context object where it's required - Introduce RenderState (which has ShaderState) to acquire/change shader related data (Region) - Shader Cleanup: User import for common stuff; use req. version - Reduce/remove data copy/recreation in *Region implementation - UI/RIButton: Use defaults I like :)
