The old xor drawing mode of QD went away with Quartz, although I
think they finally added it back within the last year or so, although
I can't find it now. Sure, in most cases repeatedly erasing and
redrawing path sketches when creating/reshaping a shape is fine and
not a big hit on performance, but QD's xor drawing produced results
that were easier to see and understand, like when a frame covers the
bits beneath it that you're trying to see; QD simply inverted them so
you could still tell what they were, but drawing with Quartz over the
top obliterates them.
