The purpose of this test is to test animation of attributes points and fill-rule.
The test consists of 2 sub-tests. The first test is a polygon shaped as a digit. The polygon
has an animation on its vertex points which morphs the polygon between the numbers 1, 2, 3
and 4. The gray outlines indicates the expected position of the polygon at 1, 2, 3 and 4s.
The second test is 4 paths in a u-shape. They have animated fill-rules. There initial
fill-rules are, from left to right, nonzero, evenodd, evenodd (by default value) and evenodd
(by default value) The expected result is that one path at a time is filled. The other three
paths are not filled but have the u-shape. Which path that should be filled at
which time is indicated by the number above it (indicating time in seconds). To enhance the
difference between the filled path and the rest, the filled path should always have the
same color as the morphing polygon. This is achieved by a discrete color animation.
