LibWeb: Begin SVG element support This commit starts adding a basic SVG element. Currently, svg elements have support for the width and height properties, as well as the stroke, stroke-width, and fill properties. The only child element supported is the path element, as most other graphical elements are just shorthand for paths.

LibWeb: Move SVGPathElement methods into SVGGeometryElement From the spec: > Interface SVGGeometryElement represents SVG elements whose rendering > is defined by geometry with an equivalent path, and which can be > filled and stroked. This includes paths and the basic shapes. - https://svgwg.org/svg2-draft/types.html#InterfaceSVGGeometryElement Making them all create an SVGPathBox, and return a Path from get_path(), means we can implement the "basic shapes" using the path system we already have. :^)

LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated This is a monster patch that turns all EventTargets into GC-allocated PlatformObjects. Their C++ wrapper classes are removed, and the LibJS garbage collector is now responsible for their lifetimes. There's a fair amount of hacks and band-aids in this patch, and we'll have a lot of cleanup to do after this.

LibWeb: Port painting to use the new Skia-backed Gfx::Path SVG and and CSS border rendering now sits on top of SkPath instead of the old Gfx::DeprecatedPath. Due to an imperceptible (255, 255, 255) vs (255, 254, 255) color diff in one ref test, I changed that test to not depend on border rendering for a positive result, since that was incidental.
