I've mentioned before that adding full-scene antialiasing one way or
another might be the right way to solve this problem in the most
general case.

But, if your scenes are strictly 2.5D, (that is, each object exists in
a plane at a constant Z value), then you might likely be able to
achieve seam-free rendering by using the CAIRO_OPERATOR_SATURATE
operator and rendering your objects in a similar order as is done for

I haven't played with this myself personally, so I won't comment more
on the specifics, (as I would likely get them wrong). But it is
something that you should look into before taking the performance hit
of FSAA, (or the quality hit of eliminating antialiasing).
