I have no idea how drawing XPMs and Bresenham lines are related, but if
you could point me to the code, I could try to investigate.

The alternative would be to draw the lines as before, but have an
additional conditional in the error pixel section, which will prevent
the overflow I addressed.  However, that will have some (small)
performance impact.
