[PyMOL] Mac Flicker Issue Workaround

[Warren D. <wa...@de...>]

Mac users:

We lucked out and obtained a little help from an off-duty Apple engineer
today who figured out how to work around the issue in 10.4.3.  It was
one of these combined bugs -- we weren't doing things sensibly in PyMOL,
and the ATI driver wasn't quite complying with normal OpenGL behavior
with respect to screen updates.

They changes seem to have done the trick, so I have posted an updated
MacPyMOL build at:

Please let me know if this does NOT solve the issue on your machine.
Also, since I had to change the lighting and draw-buffer code, please
let me know right away if anything strange or new surfaces.

Cheers,
Warren
