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: Rename Layout::BlockBox => BlockContainer There's a subtle difference here. A "block box" in the spec is a block-level box, while a "block container" is a box whose children are either all inline-level boxes in an IFC, or all block-level boxes participating in a BFC. Notably, an "inline-block" box is a "block container" but not a "block box" since it is itself inline-level.

LibWeb: Rename LayoutNode classes and move them into Layout namespace Bring the names of various boxes closer to spec language. This should hopefully make things easier to understand and hack on. :^) Some notable changes: - LayoutNode -> Layout::Node - LayoutBox -> Layout::Box - LayoutBlock -> Layout::BlockBox - LayoutReplaced -> Layout::ReplacedBox - LayoutDocument -> Layout::InitialContainingBlockBox - LayoutText -> Layout::TextNode - LayoutInline -> Layout::InlineNode Note that this is not strictly a "box tree" as we also hang inline/text nodes in the same tree, and they don't generate boxes. (Instead, they contribute line box fragments to their containing block!)

LibWeb: Make SVG <svg> elements behave as CSS replaced elements This makes SVG-in-HTML behave quite a bit better by following general replaced layout rules. It also turns <svg> elements into inline-level boxes instead of block-level boxes.

LibGC+Everywhere: Factor out a LibGC from LibJS Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root

LibWeb: Make the layout tree GC-allocated This removes a set of complex reference cycles between DOM, layout tree and browsing context. It also makes lifetimes much easier to reason about, as the DOM and layout trees are now free to keep each other alive.

LibWeb: Add SVGFormattingContext to handle SVG box trees Instead of trying to layout SVG boxes as if they are regular CSS boxes, let's invent an "SVG formatting context" and let it manage SVG boxes. To facilitate this, Layout::SVGBox no longer inherits from ReplacedBox, and is instead a simple, "inline-block" style BlockBox.
