As far a speed goes, what's the relative advantage of using PaintRgn() compared
to using CopyBits() (on a stored bitmap of the painted region)? Obviously, as
the region gets more complex, PaintRgn() gets slower. When's the cutoff? I'm
also drawing in blend mode, if that has any effects.

Thanks in advance.
