  Message : Enable [[nodiscard]] for gl::Error. This forces all return values to be checked for gl::Error. Requires quite a bit of minor refactoring. I also added a macro to swallow an error without returning from a function. We could look at storing the errors in the Context at some point, since almost always when we're generating errors that we need to discard we have access to the Context as a parameter.
