fail - measured over 21440 pixels carrying ink in either image.
These results are not meaningful. This check renders a single static frame, and nothing in a test document records which moment in time its reference image was captured at - so a correct SMIL implementation and a broken one are equally likely to mismatch. Animation behaviour is covered by dedicated unit tests instead; see ctgnz/foxglove#208 for a real measurement methodology, still to be worked out.

Difference
In the difference panel, red marks pixels that
differ beyond tolerance and grey marks matching content. The tinted band, where present, is the
<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.
What this test checks
The test passes if: Each animated element (the line, circle, three-segment polyline, image and the two rectangles) is transformed with a continuous animation over three seconds. The size and shape of each element must start off as shown by the silhouette at the start of the arrow, and must end up as shown by the silhouette at the end of the arrow. The fill of the two rectangles is animated over three seconds from white to blue.
