Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *

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!)

LibHTML: Add LayoutNode classes for "display: list-item" and its marker This patch removes the hard-coded hack for "display: list-item" from LayoutBlock and adds LayoutListItem and LayoutListItemMarker. Elements with "display: list-item" now generate a LayoutListItem, which may then also generate a LayoutListItemMarker if appropriate. :^)

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.

LibWeb: Make layout nodes refcounted Move the layout tree from GC allocation to refcounted ownership so removed layout and paint subtrees are destroyed synchronously instead of waiting for the next GC sweep. This dramatically reduces GC memory usage peaks after layout tree churn and makes it easier for memory use to fall back after large document updates. Update layout factories, tree traversal, SVG layout node creation, paintable back-pointers, and pseudo-element layout links to use RefPtr ownership. Make display: contents follow the same shape as Blink and WebKit: the element itself does not create a layout node, and its children are flattened into the nearest layout parent. Wrap direct non-whitespace text in an anonymous inline node when the boxless element contributes inherited style to that text. Use an internal inline wrapper for display: contents pseudo-elements so generated content can still participate in layout, painting, hit testing, and pseudo-element queries. Keep CSSOM reporting the computed display value from the pseudo style, not the internal wrapper. Remove the retained out-of-tree layout node list and its testing hook, since the flattened model does not need a side owner for boxless elements. Add coverage for inherited text style, dynamic insertion order, pseudo-element hit testing, and computed style queries.
