// These particular test cases can get stuck in infinite recursion due to limited fp32
// precision. (Although they will not with the provided tessellationPrecision values; we had to
// lower precision in order to avoid the "viewport size" assert in PreChopPathCurves.) Bump the
// tessellationPreciion up to 4 and run these tests in order to verify our bail condition for
// infinite recursion caused by bad fp32 precision. If the test completes, it passed.
