  The meaning of this function is entirely unclear.

  And I think all of the fix should go in here.

  As far as I can tell, all we need to do is chop the line into the geometry 
of the view.  This function can already do all the important calculations 
internally if it just makes use of the QPoint argument.  Unfortunately Qt3's 
QRect doesn't ::intersect() well when it isn't normalized, so this patch is 
more complicated than it should be.

  One other bug I noticed is that the viewline object doesn't track moves 
properly, so it sometimes gets desynchronized.  This patch also fixes that 
problem.
