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.

LibHTML: Flesh out <img> element with LayoutImage and LayoutReplaced This patch adds parsing of <img> into HTMLImageElement objects. It also adds LayoutImage and its parent class LayoutReplaced, which is going to represent CSS "replaced elements."

AK: Add a forward declaration header You can now #include <AK/Forward.h> to get most of the AK types as forward declarations. Header dependency explosion is one of the main contributors to compile times at the moment, so this is a step towards smaller include graphs.

LibWeb: Split out image loading logic from HTMLImageElement Since more DOM nodes are going to want to load images (<object>, ...) this patch splits out the image loading logic into an ImageLoader class and then HTMLImageElement simply has an ImageLoader. LayoutImage is then given a const ImageLoader& at construction and can then provide layout and rendering for many kinds of DOM nodes.

LibWeb: Move HTML object model stuff into LibWeb/HTML/ Take a hint from SVG and more all the HTML classes into HTML instead of mixing them with the DOM classes.

LibHTML: Mark image bitmaps outside the visible viewport as volatile When the visible viewport rect changes, we walk the layout tree and check where each LayoutImage is in relation to the viewport rect. Images outside have their bitmaps marked as volatile. Note that the bitmaps are managed by ImageDecoder objects. If a bitmap is purged by the kernel while volatile, we construct a new ImageDecoder next time we need pixels for the image.

LibWeb: Use HTML::AttributeNames::foo instead of FlyString("foo") To avoid the costly instantiation of FlyStrings whenever we're looking up attributes, use the premade HTML::AttributeNames globals. :^)

LibHTML: Implement basic layout for inline <img alt> LayoutReplaced objects can now participate in inline layout. It's very hackish, but basically LayoutReplaced will just add itself to the last line in the containing block. This patch gets rid of the idea that only LayoutInline subclasses can be split into lines, by moving the split_into_lines() virtual up to LayoutNode and overriding it in LayoutReplaced.

LibDraw: Put all classes in the Gfx namespace I started adding things to a Draw namespace, but it somehow felt really wrong seeing Draw::Rect and Draw::Bitmap, etc. So instead, let's rename the library to LibGfx. :^)

const Gfx::Bitmap* bitmap() const;
LibHTML: Support rendering <img src> with file:// URLs We can now show images loaded from local file:// URLs. Pretty neat :^)
