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! :^)
