Question: How can one use offscreen bit maps that appear and disappear during
a program and avoid heap fragmentation? I notice that 
offScreen.portBits.baseAddr must be a pointer, not a handle. Should I allocate
a handle anyway, and lock and dereference it when I need to draw on the
bit map or CopyBits() from it?

Any wisdom you might have would be appreciated.
