If you carefully read SALAD, analyze the Line-A variables (especially
the ones at negative offsets from the line-A variable base pointer,
which were previously undocumented), and experiment some, you will find
that you CAN do this.  The code is parameterized enough that this kind
of thing is possible.  You will still have to take care of clipping and
redrawing...  Read carefully and experiment, and especially experiment
with accessories like the control panel active on the screen, to see if
you got redraws working correctly.
