Attachment: testcase 2

This reduced & animated testcase has a scale transform hovering around 1.

There seems to be a threshold (at 1, I think?) where the pattern switches rendering, in my Nightly 28.0a1 (2013-11-27)

Neither Chrome & Opera (Presto) exhibit the pattern rendering-switch behavior. They both match Firefox Nightly's "larger-scale" rendering, all of the time.
