LibWeb: Add initial support for SVG `<textPath>` This patch adds basic support for the SVG `<textPath>`, so it supports placing text along a path, but none of the extra attributes for controlling the layout of the text. This is enough to correctly display the MDN example. 2023-12-17 18:35:21 +00:00			`/*`

LibWeb: Make computed style data refcounted Move ComputedProperties and CascadedProperties out of the GC. They no longer contain strong references to GC-managed data. Keep computed styles alive from DOM elements and animation updates with RefPtr. Pass style into layout constructors by reference, since layout only copies the values it needs while building nodes. Use GC::Weak for cascade source links, so entries no longer keep the style declaration or shadow root alive. 2026-06-06 14:03:41 +02:00			`SVGTextPathBox::SVGTextPathBox(DOM::Document& document, SVG::SVGTextPathElement& element, CSS::ComputedProperties const& style)`

LibWeb: Make Paintable tree ref-counted The Paintable tree and its supplemental painting data structures were GC allocated because that was the easiest way to manage it and avoid leaks introduced by ref cycles. This included the Paintable subclasses themselves plus StackingContext, ChromeWidget, Scrollbar, ResizeHandle, and scroll-frame state. We are now trying to reduce GC allocation churn on layout and painting updates, so keeping this short-lived rendering tree outside the JS heap is a better fit. Move Paintable to RefCountedTreeNode, make painting helpers ref-counted or weakly reference Paintables, and update the layout and event-handler call sites to use RefPtr/WeakPtr ownership. 2026-05-07 13:38:05 +02:00			`RefPtr<Painting::Paintable> SVGTextPathBox::create_paintable() const`
