/* 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.
