Commit c29968bb by Jamie Madill
Options

Refactor FBO related entry points.

Change the validation to the consistent style for easy auto-generation and make the context itself implement the entry points. This will more easily allow us to sync state without passing the Context to the Texture methods, or doing work in the entry point.
