Bug 269545 – Return initial value for `stop-color` instead of `transparentBlack`

• Status: RESOLVED
• Resolution: FIXED
• Component: SVG

Hi Team,

While looking into `stop-color` failures, I noticed that we return `transparentBlack', while I think it would be better to return `Color:Black` since it is initial value as per web-spec:

Web-Spec: https://svgwg.org/svg2-draft/pservers.html#StopColorProperties

Initial: Black

Our current code: https://searchfox.org/wubkat/rev/c40451f6052e2805fb1c6abfb61fa322c67caf5b/Source/WebCore/svg/SVGStopElement.cpp#90

We should change it to `Color:black`.

transparentBlack -> static constexpr auto transparentBlack = SRGBA<uint8_t> { };

While

black -> static constexpr auto black = SRGBA<uint8_t> { 0, 0, 0 };

Which makes more sense and aligned with web-spec.

Thanks!
