FULL-SCREEN MODE

    It is sometimes useful, as in photographing or capturing an image,
to have the resolution corresponding to the full screen.  There is
therefore provided the feature that when the pointer is in a graphics
window and the F1 key is pressed, then the current graphics in that window
becomes rendered in full-screen mode.  Pressing the same key, F1,
while in the full_screen window causes a return to the graphics 
window from which the full_screen mode was invoked.  All graphical
features, such as picking, translating, rotating and zooming,
are retained in the full-screen mode.
