When showing failure images for ref tests for WK2 tests, the images are flipped (upside-down). This implies that we're comparing upside-down images, which is harmless but wrong.
This is still occurring on Mac (looking at the builder output), but I can't reproduce it on GTK. Seems as it's Mac-specific.
--pixel-test images are also flipped, breaking all pixel tests :(
