test/coverage: Exercise invariance under mirror symmetry
Massimo noticed that the record/record-flip were not being rasterised as
identical mirror images due to a half-subpixel offset in the tor scan
converter. This test attempts to reproduce this error by rendering a
rhombus around the origin of each cell (that is it generates 4 mirror
images of a triangle in the 4 different orientations0. The expectation
is that each pixel in the group is lit identically as the coverage is
identical.
