Right now, we're using #mask hack to cover irrelevant area to hide subtle differences in reftests in order to pass. We should use fuzzy annotation instead.

Per bug 1350927 comment 2, for the reftests-shoehorned-into-mochitest tests that use "videomask.css", it seems like in fact the #mask was originally there to cover *not-at-all* subtle differences -- it was covering a throbber whose rotation state was impossible to predict.

I think that throbber isn't part of our controls anymore, though, so we might just be able to just remove the mask and be done with it.
