As someone who would have to write such higher-level code, I'd
appreciate the proposal of a feasible algorithm.

I hadn't originally intended to revive this thread until I had a patch
in hand; talk is cheap, working code speaks volumes.

My current intent is to add a function to the image backend (only), to
disable/enable partial coverage simulation.  Mostly it'll just require
using a different trapezoid drawing function when simulation is turned
off.

On the other hand, have you considered how aliased_lineto might be
implemented in the various backends?  I'm not certain it's possible for
many of them.
