This also ignores a clippy warning for a new function (and a similar
existing one), until this code can be refactored to use temporary Rust
strutures to carry display list building state.
There are a few new test failures here:
- FAIL [expected PASS] /css/css-images/image-set/image-set-conic-gradient-rendering.html
- FAIL [expected PASS] /css/css-images/image-set/image-set-repeating-conic-gradient-rendering.html
These fail because Servo does not yet support `image-set()`.
- FAIL [expected PASS] /css/filter-effects/filter-function/filter-function-conic-gradient.html
- FAIL [expected PASS] /css/filter-effects/filter-function/filter-function-repeating-conic-gradient.html
These fail because Servo does not support the very early filter effects
specification.
- FAIL [expected PASS] /html/canvas/element/manual/fill-and-stroke-styles/conic-gradient-rotation.html
- FAIL [expected PASS] /html/canvas/element/manual/fill-and-stroke-styles/conic-gradient.html
These fail because this change only adds support for CSS conical
gradients. Another set of changes will be necessary to support this for
Canvas.
