    reftests: fix the linear-gradient reftest
    
    Don't use a repeating linear gradient, since it can't be easily
    reftested against a non-repeating one for the reasons described in the
    test header.
    Instead, add a separate test for repeating gradients (against another
    repeating gradient).
    
    This makes the test pass, so it can be added to the Makefile now.

  * This means that you cannot:
  * ... add extra color stops, even if they'd be invisible
  * ... mirror the gradient (ie 'to left, red, green' 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.
