I have reported that first error a few months ago, and nobody has commented
on it. I hope somebody knows what image that is supposed to be for.
The second error has popped up several times before, and we don't seem to
address it properly. The difference between the expected and the resulting
images has a definite structure to it, suggesting that something changed.
Either there is something wrong with the original image, or there is
something wrong with the current image. If we figure that the current image
is correct, and that there was something wrong with the previous image, then
we should update the image in the test suite.
