Good Idea to create a new driver based on Mapnik ;-)
I never heard about the C-API for Mapnik but they should be useful. I
could ask to Dane what is the stability of the C-API.
Is there any way to write the driver in Python (the Mapnik Python API
are probably more stable, used and tested than the C-API)
