Test case

This testcase shows that it's a bug when farthest-side is used. The top gradient uses:
CGGradientCreateWithColorComponents - colors [0.00, 0.50, 0.00, 1.00, 0.00, 0.00, 1.00, 1.00] locations [0.71, 0.71] numberOfStops 2

The bottom one uses:
CGGradientCreateWithColorComponents - colors [0.00, 0.50, 0.00, 1.00, 0.00, 0.00, 1.00, 1.00] locations [1.00, 1.00] numberOfStops 2

but they should be the same.

attachment 463254 [details] doesn't seem to use farthest-side at all fwiw.
Comment 5 Simon Fraser (smfr) 2022-10-31 09:42:31 PDT 
That needs reducing to the single gradient that renders incorrectly.
