/* One caveat that apply to cairo gradients, and make things therefore
 * untestable:
 *   The start and end points must be identical when drawing
 * This means that you cannot:
 * ... add extra color stops, even if they'd be invisible
 * ... mirror the gradient (ie 'to left, red, lime' vs 'to right, green, red')
 * ... test a repeating gradient against a non repeating one
 * and probably a bunch of other things.
 * These things can cause off-by-one rounding errors in pixman (and probably
 * your GPU, too) and that'd trigger test failures.
