In MacPaint the tricks for managing to move an object around are much more
sophisticated than XOR.  An entire copy of the bit image being over
drawn is maintained.  During each cycle the saved copy is restored and then
the tool's dynamic portion is smashed into that.  Of course this requires
that it be real quick and/or use the alternate video area.
