Summary

This change brings Chromium code in line with the latest W3C spec for SVGGeometryElement and SVGPathElement in terms of usage of DOMPointInit over SVGPoint for getCharNumAtPosition, isPointInFill, isPointInStroke. The change has already landed: https://chromium-review.googlesource.com/c/chromium/src/+/6284886 Firefox and Safari already have this live making this a fairly safe change to land. Details for both added under Signals for both.

Motivation

To bring Chromium code in line with the latest W3C spec for SVGGeometryElement and SVGPathElement in terms of usage of DOMPointInit over SVGPoint for getCharNumAtPosition, isPointInFill, isPointInStroke.

Standards & signals

Specification: https://svgwg.org/svg2-draft
Firefox: Shipped/Shipping — Firefox uses DOMPointInit already in the corresponding API: https://developer.mozilla.org/en-US/docs/Web/API/SVGGeometryElement/isPointInFill Also, WPT has been passing for Firefox indicating that they have implemented this already: https://wpt.fyi/results/svg/types/scripted/SVGGeometryElement.isPointInFill-01.svg
Safari: Shipped/Shipping — Webkit (Safari) already uses DOMPointInit in these APIs. Here is the commit link for one of the APIs: https://github.com/WebKit/WebKit/commit/7589919c57641e1e3dac86872171d4d681e3f2d0 Also, WPT has been passing for Safari indicating that they have implemented this already: https://wpt.fyi/results/svg/types/scripted/SVGGeometryElement.isPointInFill-01.svg
