Add support for the "color-interpolation" attribute for SVG gradients
https://bugs.webkit.org/show_bug.cgi?id=234783
rdar://87294645
Reviewed by Simon Fraser.
SVG gradients now properly respect the color-interpolation attribute
as specified in the SVG specification. Previously, all gradients were
hardcoded to interpolate colors in sRGB space, regardless of the
color-interpolation attribute value.
It fixes both:
* New Layer-Based SVG Renderer (LBSE)
* Legacy SVG Renderer
with color-interpolation="sRGB" or color-interpolation="auto"
gradients interpolate in sRGB space
(using ColorInterpolationMethod::SRGB, the default)
with color-interpolation="linearRGB"
gradients interpolate in linear RGB space
(using ColorInterpolationMethod::SRGBLinear)
* LayoutTests/TestExpectations:
This fix enables the following WPT test to pass:
