    A quick hack around this is to call HideCursor before the graphics 
    operation, then ShowCursor when you are done.  But, unless done
    carefully, you'll end up with a flickering cursor.

This isn't a hack; it's a technique.  If you look closely, you will notice
that Quickdraw does this when you draw something and the mouse cursor is
over the current window (GrafPort).  If you are "too careful" you will end
up with slower drawing primitives.
