Tape drive and SGI weirdness

My SGI O2 decided to bestow upon me a special wraparound image. The toolchest window on the top right should be on the top left. You can see the gr_osview wrap from the bottom right to the bottom left. The strange thing about this was that the mouse pointer showed in the correct place, but everything else drew incorrectly. Everything went back to normal with a hasty 'endsession -f'.
