Now that Soeren has made a release of pixman with the extended blend
mode support, I'd like to land this with a corresponding pixman
dependency bump.

However, that series of patches, as it stands, contain a series of
broken steps and would break future bisection. Plus, I don't like the
separate changes to add tests and documentation after the introduction
of the operators.

What I'd like, trying to preserve original authorship as much as
possible (failing that, to give due credit in the commit logs) is:

1. Add core support and bump pixman dependency.
   i.e. add public API and image->pixman support, and the test case.
   Confirm that all the backends correctly fallback.
2. Add backend specific code.

Thank you Carlos, for pushing this forward.
