Hash : 5d601382
Message : Simplify formatutils.h by exposing the info structures. Removed all the separate query functions and simply expose the internal info structures. This reduces the number of std::map/std::set operations that were hidden behind the API. Moved the validation tables for ES3 format combinations and effective internal formats into validationES3.cpp so that formatutils.h only has generic GL format queries.
