Pango supports shears. Pango handles bounding box rotations. Pango
scales under zoom. I think you have some difficulty in your code.

Perhaps one point of confusion is that Metrics in Pango are reported
in *user* space ... that is, before the transformation.

Why would I pull in a moderately large, hard to use, scheduled-to-be-
replaced library to avoid what ended up being 160 lines of code
including documentation?
