11 November 2000
+ Got opengl sorta working, when I should be working on my
OS project involving semaphores. Oops.
2 November 2000
+ Continued re-writing the level_1 engine that I started last week.
+ Re-wrote frame limiter. Managed to make it a lot less jumpy.

Known Bugs:
8bpp palette switching not as smooth as it could be.
Volume controls on option menu don't do anything yet
I get higher FPS on a 486 than my k6-2+! Need to figure this out.
Frame limited code is limited. Need to think about this some more.
