Work around a y-invert bug on Macs w/ Intel GPU

On Macs running OS X 10.6 and 10.7 with Intel HD Graphics 3000, some
screens or parts of the screen are displayed upside down. The exact
conditions/sequence that triggers this aren't known yet; I haven't
been able to reproduce it in a standalone test. This also means I
don't know whether it is a driver bug, or a bug in the OpenglRender or
Translator code that just happens to work elsewhere.

Thanks to for a patch this change is based on.
