I'd recommend moving the cairo rendering code into Mesa and have Mesa
implement and export some kind of a low-level cairo library.

Please note that Gallium doesn't support Intel GPUs, which may be a
significant part of your user base.

A cairo GL backend is probably going to be your best choice if you
want hardware support everywhere.
