I tried with and without-L or -R and the cusor was always 90 degrees out
with actual pointer moevment. This is what the pointer movement vs
cursor movement is,whether landscape or portrait, without my fix.
movement cursor
+x = +y
-x = -y
+y = -x
-y = +x
With my fix, the cusor moves with pointer in landscape or protrait mode.
Need to try -D once I get cvs leaving the mouse on the screen. To bad
the Boss doesn't feel that way.

I'll look there and see what I find. Actually, looking for all these
problems has taught me a lot about the code.
