Chris Wilson	5c03b20732	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.
