Note that animateMotion-flattening-1.svg has yet to be pushed (waiting to make sure the fails-if clause pleases try server)

The failure is in the extreme bottom strip of pixels

Testcase has:
 rgb(1,255,1)
whereas reference has:
 rgb(0,255,0)

So it's *very* close. Might be worth using fuzzy-if instead of fails-if, since it's so close. (That way, we'll be able to catch actual failures in this test on Win8.)

Still, odd that that bottom strip isn't matching. Does this reftest do anything near the bottom of the window?

It moves a red rectangle from roughly the top-left of the viewport to the bottom/bottom-right so it could well be an artifact from moving the rectangle which may have been layerized.

Oh, except that the whole test is paused and seeked. So maybe that has nothing to do with it.
