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.

if (lowercase_tag_name == HTML::TagNames::form)
LibHTML: Implement basic <form> and <input> element support This patch adds "submit" inputs and default (text box) inputs, as well as form elements that can be submitted. Layout of input elements is implemented via a new LayoutWidget class that allows you to put an arbitrary GWidget in the layout tree. At the moment, the DOM node sets the initial size of the LayoutWidget, and then the positioning is done by the normal layout algorithm. We also now support submitting a <form method="GET">, which does a full replacing load with a URL based on the form's action + a query string built from the name/value of input elements within the submitted form. This is pretty neat! :^)

if (lowercase_tag_name == HTML::TagNames::br)
LibHTML: Implement the <br> element for line breaking The <br> element will produce a special LayoutBreak node in the layout tree, which forces a break in the line layout whenever encountered. This patch also makes LayoutBlock use the current line-height as the minimum effective height for each line box. This ensures that having multiple <br> elements in a row doesn't create 0-height line boxes.

if (lowercase_tag_name == HTML::TagNames::iframe)
LibWeb: Start adding support for the <iframe> element! :^) This patch introduces a bunch of things: - Subframes (Web::Frame::create_subframe()) - HTMLIFrameElement (loads and owns the hosted Web::Frame) - LayoutFrame (layout and rendering of the hosted frame) There's still a huge number of things missing, like scrolling, overflow handling, event handling, scripting, etc. But we can make a little iframe in a document and it actually renders another document there. I think that's pretty cool! :^)

if (lowercase_tag_name == HTML::TagNames::canvas)
LibWeb: Add <canvas> element and start fleshing out CRC2D This patch adds HTMLCanvasElement along with a LayoutCanvas object. The DOM and layout parts are very similar to <img> elements. The <canvas> element holds a Gfx::Bitmap which is sized according to the "width" and "height" attributes on the element. Calling .getContext("2d") on a <canvas> element gives you a context object that draws into the underlying Gfx::Bitmap of the <canvas>. The context weakly points to the <canvas> which allows it to outlive the canvas element if needed. This is really quite cool. :^)

return adopt(*new HTMLCanvasElement(document, lowercase_tag_name));
LibWeb: Add basic <object> element support This patch implements a simple <object> element with fallback content. If the URL from the data attribute fails to load (including 404), we render the DOM tree inside the <object> as fallback content. This works by generating a different layout tree for the <object> depending on the state and success of the data load. Since we cannot currently do incremental layout tree updates, we have to force a complete layout tree rebuild when the resource load finishes/fails.
