Just an update. I've found an ABI breakage in Cairo::Context::transform()...

I built papyrus against 1.6.4, and it rebuilds fine against cairomm 1.8.0.
But, when conexus builds it's getting:

/usr/lib/gcc/i386-redhat-linux/4.3.2/../../../libpapyrus.so: undefined
reference to `Cairo::Context::transform(_cairo_matrix const&)'

Rebuilding papyrus against cairomm 1.8 resolves the symbol, so I don't
think it's an API issue.... looks like an ABI issue.

cairomm should probably have the soname bumped.
