In most, if not all, cases where the WebKit WebGL implementation is raising
JavaScript exceptions, for example during argument validation, it instead needs
to fabricate the appropriate GL errors. Higher-level code can check the GL
error state after each call and explicitly throw an exception. 

This is important to fix as soon as possible to make the implementation spec
compliant and, in particular, so that the working group doesn't release bogus
tests along with the first public draft of the spec.
