Hi Hazen:
I suggest you put the above code and a README.extcairo file concerning the
extcairo device in examples/c as an initial demonstration of what is
possible with the extcairo device. Later if you have time/inclination you
could add more to the example, but it is good to make a start right away
rather than letting this code get lost on this mailing list.
