Andre, that was a HUGE amount of work and we thank you for that.  It is
checked into GIT in the Manual with only trivial changes so you might want
to check it out to make sure I did not make any mistakes.  Trivial changes
were just typo of 35 "mmm" and "aspectt" (I think your keyboard is doing
the same thing that mine is, with adding extra letters!). And a couple of
other things like "\CGG{}Cinelerra..a" instead of just "\CGG{}" and I
changed "act on" to "click on" for Apply.

It is good placement the way you put it and fits in really well.

I would hate to see this section never make it into the manual as I think
it would be advantageous to have a good explanation of anamorphosis -- I am
concerned that Raffaella Traniello website may someday disappear (after all
it does say "Grandma" on it).
