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 :)
