What is the reason for this change? Also, you should use rebase to move
squash this into the previous commit; it doesn't make sense to put it with
this one.

Maybe say something like "%s(invalid renderbuffer name"? I typically
prefer to throw this error earlier so that you can print out the name of
the renderbuffer in the error message, too, but that's not a big deal.
