You have to look at the code very carefully.  But, if there is a spot where
there is a scale function already done, change the x or y value by putting
a `neg' after that number.  You will also have translate the coordinates
of the x or y, whichever you negated.  I suggest doing the translate before
the scale, otherwise you have to remember to use a negative of the direction
you really want to go.

Good luck.
