A GLUI_Control-drawing sentinal object.
On creation, saves the current draw buffer and window.
On destruction, restores draw buffer and window.
This is way nicer than calling save/restore manually.

/** Just drop a GLUI_DRAWINGSENTINAL_IDIOM at the start of your draw methods,
and they'll return if we can't be drawn, and
automatically save and restore all needed state.
