Core Graphics has a bug with the extend color for radial gradients, which we'll need to work around. See attached testcase.

This bug is also apparent in LayoutTests/svg/batik/paints/gradientLimit.svg
Comment 4 Simon Fraser (smfr) 2011-01-03 21:36:35 PST 
This patch will require new pixel results for various SVG, CSS and canvas tests. Also, some of the canvas/philip tests break (and some get fixed).

rdar://problem/8814089 was fixed in 2011 but we still don't render the test case correctly.
Comment 7 Jon Lee 2019-01-17 17:28:30 PST 
Both software and hardware paths fail in the first two (colored) cases.

Safari 16 and Safari Technology Preview 154 still differ from Chrome Canary 108 and Firefox Nightly 107 for two first row cases in attached test cases. Just wanted to share updated testing results. Thanks!
