Previously, the SVGPathPaintable walked up the DOM tree to find the
containing SVG, however, this does not hold for masks/clipPaths that
are not local to the current SVG. Instead, we should walk the layout
tree where we should always be able to find the current SVG as an
ancestor.
This works just like masks, with a few more (spec imposed) limitations.
All the style properties on the contents of a <clipPath> are ignored,
and instead we just paint the "raw geometry" (as all black), then apply
that as an alpha mask to the target element.
If the element has both a `mask` and `clip-path` set, we compute the
masking area as the intersection of the mask rect and clip rect, then
apply the clip mask to the `mask` (producing a combined mask).

This change modifies hit_test() to no longer return the first paintable
encountered at a specified position. Instead, this function accepts a
callback that is invoked for each paintable located at a position, in
hit-testing order.
This modification will allow us to reuse this call for
`Document.elementsFromPoint()` in upcoming changes.
Previously, we were handling viewBoxes/viewports in a slightly hacky
way, asking graphics elements to figure out what viewBox to use during
layout. This does not work in all cases, and can't allow for more
complex SVGs where it is possible to have nested viewports.
This commit makes the SVGFormattingContext keep track of the
viewport/boxes, and it now lays out each viewport recursively, where
each nested `<svg>` or `<symbol>` can establish a new viewport.
This fixes some previous edge cases, and starts to allow nested
viewports (there's still some issues to resolve there).
Fixes#22931
This makes use of the new Gfx::Path::text() to handle SVG text elements,
with this text is just a regular path, and can be manipulated like any
other graphics element.
This removes the SVGTextPaintable and makes both <text> and geometry
elements use a new (shared) SVGPathPaintable. This is identical to the
old SVGGeometryPaintable. This simplifies painting as once something is
resolved to a Gfx::Path, the painting logic is the same.
