Summary Gradient offsets are off if compositing operator != source-over

Reported 2014-03-06 01:32:41 PST
Created attachment 225966 [details] Example. Gradient should be in center of the canvas. The gradient offsets are off if compositing operator != source-over. It looks like the gradient space is not mapped to the canvas space correctly anymore.

I looked at the test case. It seems very unlikely that this Canvas only thing (even limited to the context of the ImageBuffer) influences the transition test. This seems to be a false negative.
