Known Bugs:
use of mac#rect and associated rectangle functions can cause the app to crash. The problem looks to be improper dereferencing of the memory pointer to the rectangle which then becomes a time bomb until the next garbage collection, since the app will work for some (random) time before it suddenly dies. The best way to work around this problem is not to recycle the rectangular region but create a new one every time one is needed. The probability of a crash becomes very much smaller, but nonzero.
