[PyMOL] High Resolution Interface

Dear all,

I want to take high resolution screenshots of the PyMol interface for
figures in a methods paper where PyMol is used for some steps.  Is
there a way to make the elements of the interface display 4 times as
large so I can get ~300 dpi images instead of 72 dpi?  I have access
to Linux, OS X, and Windows, so answers on any of these systems will
be useful.

Thanks,
David
