Yes, of course you can just use PyCairo rather than a canvas.  It's just
more work that way.  I ended up having to go this route at work because
we're stuck on RHEL 5 which has ancient versions of GTK+ and Cairo, and
all the nice new canvases I tried require newer versions.

Last time I checked there were no API docs for PyCairo.  There are a
couple of simple tutorials for it, and then there are the C API docs for
Cairo.  Follow the Python tutorials to learn the basics, and then learn
how to translate the C API docs to Python.  It's annoying to have to do
that, but not really difficult.  If you're unhappy with that situation
then please contribute some PyCairo docs.
