I suspect this caused an image failure on:
virtual/threaded/compositing/visibility/visibility-image-layers.html

http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40...

The image change is imperceivable so I'll rebaseline it.

Re-landing this. Hopefully not causing the PDF unit test failure that was the
reason for reverting this last time. If it does, please ping me before reverting
this change.
