Summary

Added a work around for detected driver issue.

It seems like the AMD Adrenalin 19.9.2 driver doesn't respect selected glDrawBuffers and only clears the first color buffer.
This patch will add a work around to in this case clear every buffer one by one.

@Clément Foucault (fclem) Bug has been confirmed and have been solved at AMD. Their advice: Tell our users to not use that driver :-)
... now how to limit the number of bug reports the upcoming month orso.
I would suggest to not commit this work-around.
