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. 2020-01-18 09:38:21 +01:00			`/*`

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 * 2021-04-22 01:24:48 -07:00			`* SPDX-License-Identifier: BSD-2-Clause`

LibHTML: Add a LayoutStyle object (computed style for a LayoutNode.) 2019-06-16 13:44:09 +02:00			`#pragma once`

LibGfx: Rename from LibDraw :^) 2020-02-06 12:04:00 +01:00			`#include <LibGfx/Size.h>`

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!) 2020-11-22 15:53:01 +01:00			`namespace Web::Layout {`

LibWeb: Turn BoxModelMetrics into a simple struct Using getters for this thing was just cumbersome and didn't achieve anything of value so just turn it into a plain struct. 2020-06-24 11:22:34 +02:00			`struct PixelBox {`
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. 2020-12-12 21:02:06 +01:00			`float top { 0 };`
