I made some of the changes discussed earlier this week to the OSX version of GEM.
changes:
second display on and off.
the dimen is not supported by the display the context is not created. untested with PAL equipment, but should work.
message. Mainly useful for DV devices using [quality 1( to insure HighQuality.
Both the Experimental and G4 versions have these changes.
