Thanks. I added this to the test and did some further changes to it (e.g.
push_group instead of create_similar and simplified the clip).
The result is attached.

Then I noticed that cairo already has a test called "operator-source" and
thought that it would make more sense to expand it to also cover this bug
(sorry). Since this should affect all unaligned boxes drawn with operator
"source", it only needed minor modifications.
Attached are the two git commits for this (the change to the test and yet
another fix). Anyone got some comments about these?

However, even before this change "operator-source" fails for me because
apparently I don't have the right font. Is there anyone out there who has the
right font? Could that someone generate some reference images for me?
Currently, cairo has these images for "operator-source":

operator-source.image16.ref.png
operator-source.pdf.rgb24.ref.png
operator-source.quartz.argb32.ref.png
operator-source.quartz.rgb24.ref.png
operator-source.ref.png
operator-source.rgb24.ref.png
operator-source.svg12.argb32.xfail.png
operator-source.svg12.rgb24.xfail.png
operator-source.xlib-fallback.ref.png
operator-source.xlib.ref.png
operator-source.xlib.rgb24.ref.png

If no one comes up with some images, I will use my local results for the new
images and push those. Someone else can then later push the "correct" reference
images.

Cheers,
Uli
