The discrepancies in these tests appear to all be font rendering /
antialiasing, probably due to algorithmic changes in Pixman.
Some of these reference images were updated in Federico's recent patch,
so the fact that they differ on my system may indicate there may be some
system dependencies beyond just pixman, that can cause test result
variation from person to person. Ideally, these would be isolated and
the tests modified to not have such dependencies.

[In testing, I was able to reproduce Federico's results for most, but
not all, of the test images. There might be some additional
platform-specific discrepancies that need ironed out, but this is a
solid step forward in any case.
Results for a quick run against just the image backend on my system:
