Bug 1949857 [wpt PR 50878] - Add CSS Color 4 gradient options to CanvasGradient, a=testonly
Automatic update from web-platform-tests Add CSS Color 4 gradient options to CanvasGradient Add ColorInterpolationMethod, HueInterpolationMethod and premultipliedAlpha attributes to CanvasGradient as described here: whatwg/html#7947 This is done behind the flag CanvasGradientCSSColor4, as spec is not yet settled: whatwg/html#10986 Chromestatus: https://chromestatus.com/feature/5168382242193408 I2P thread: https://groups.google.com/a/chromium.org/g/blink-dev/c/6PhsIK2kxeM Gradient::ColorInterpolation is also renamed to Gradient::PremultipliedAlpha, because that's what it is. Subpixel antialiasing for test labels is being inconsistently applied on windows, so the tests are marked as failing with a bug. crbug.com/396344375 Bug: 394052224 Change-Id: I6b1092376d08c051b161f83c82d585bd03cd4131 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6226021 Reviewed-by: Chris Harrelson <chrishtr@chromium.org> Commit-Queue: Aaron Krajeski <aaronhk@chromium.org> Cr-Commit-Position: refs/heads/main@{#1423255} -- wpt-commits: fa9792e79e03bcdb6ce8a913c74981cbebe77756 wpt-pr: 50878
