Look in pango-matrix.h for the transforms.

I skimmed over the actual code, and at the current point of time it is
nothing particularly optimized: it almost looks like a copy of your code
right now.  I'd still prefer a wrapper for that (it's not inconceivable
that we might want to pass these into Pango rendering at one time, and
not having to copy anything would be an advantage) to our own code.
