Difference
<text id="revision"> legend every test carries: it renders in a fallback font this
library cannot match, so it is excluded from the comparison entirely rather than failing every test.
You should see three filtered images. Each image is the same and has the same filter applied to it. The test has passed if all the three filtered images look the same, and the filtered result shows bright white edges on a dark background. The rendered picture should match the reference image.
