There was another suggestion:

4) Draw all objects front to back, taking advantage of
   CAIRO_OPERATOR_SATURATE.

This won't be entirely general as it will only work if all objects
have a uniform Z value, (but I assume all mozilla objects have that
property).

This approach is exactly the way that OpenGL solves seam problems, (as
far as I understand), and as such it will be quite amenable to
hardware acceleration.
