#2 Graphics are very slow

[Tilmann Zaeschke]

This is most likely caused by the way that DrawStuff uses OpenGL. This is fine in C++, but causes large overheads in Java.
Running a demo with -Xprof shows that most of the time is spent in GL code, not in ode4j physics code.

Workaround for performance measurements:
Insert
DrawStuff.outputToNull();
into a demo before the first call to DrawStuff.
