// Fails on Linux with Azure/Cairo only
// The arc is drawn badly due to Cairo limitations, the error only becomes
// apparent on Linux because of anti-aliasing, probably due to X.
// The limitation is that Cairo draws arcs by stroking perpendicular to the arc,
// and at very large stroke thicknesses, this becomes a fan. Where exactly the
// 'blades' of the fan appear seems to depend on exactly how the arc is defined
// and the platform. So if the blades of the fan are where pixels are tested it
// passes the test, if the testing pixels fall in between the blades, then we fail.
// With Thebes/Cairo, we were rendering wrong, but got lucky with the test, now
// we are not so lucky.
