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 directory LibHTML => LibWeb Let's rename this to LibWeb since it aims to provide more parts of the web platform than just HTML. :^)

LibHTML: Rename LayoutStyle => ComputedStyle.

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: Store layout box model metrics as floats Instead of storing them as CSS::Lengths, we now store the resolved values for margin/padding/border/offset top/right/bottom/left with each Layout::NodeWithStyleAndBoxModelMetrics. This simplifies a lot of code since it's no longer necessary to resolve values before using them.

PixelBox BoxModelMetrics::margin_box() const
LibHTML: Add ComputedStyle::full_margin() This is an utility to easily get the full margin size (the sum of margin proper, border and padding) of an element in pixels.

PixelBox BoxModelMetrics::padding_box() const
LibWeb: Some improvements to absolute positioning Absolutely positioned blocks now register themselves with their containing block (and note that the containing block of an absolutely positioned box is the nearest non-statically positioned block ancestor or the ICB as fallback.) Containing blocks then drive the layout of their tracked absolutely positioned descendants as a separate layout pass. This is very far from perfect but the general direction seems good.
