Ok, it still doesn't work really good.
I pasted the essential parts of the code into a small demo, added a
frame to it for display and it runs just as bad as the complete thing.
The delay between movement and drawing ia about five seconds, getting
worse with the time. If you have the time to check it out for a sec and
find something problematic, please let me know. Otherwise I will have to
port the whole thing to C. Thanks in any case.

Let me get this straight. Unless you can download two images
simultaneously in under 200ms, you will not receive your degree. WTH
kind of college are you going to?
