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.

This test was added by John Hunter fairly recently. I’ll go ahead and
commit the test results from my machine – I assume they are correct
since there’s nothing special about the test.

Both the png and svg versions of this test have been updated more
recently than the pdf, so I suspect it’s ok to update it. I’ll go
ahead and do this.
