Last change on this file since 8fa9562 was 8fa9562, checked in by Alejandro R. Sedeño <asedeno@mit.edu>, 14 years ago
Added background color support to owl. If we run out of color pairs during a painting of the screen, further background colors will be silently dropped. I'm hoping this doesn't happen often. The used pair list is reset with each draw, so only what's actually on screen matters.
