Of course, a far simpler solution is to do the coordinate transformations
completely outside of cairo contexts. When I used cairo for plotting in the
past, what I did was create my own coordinate transformation matrix, to
which you can apply scaling and translation as usual, and simply apply this
transformation matrix to every coordinate before passing it down to cairo
proper. It may be a bit more typing, but it is also far more understandable
in the end.
