Attachment: WIP v1

Things to do
* Tried find a way to make ctx.drawWindow(contentWindow, ...) because there is a API for that.  I've tried to pass ctx to the content script, however, drawWindow() is not defined in ctx object after it's being passed to the content script.
* Fix broken tests e.g. browser_tabview_bug587248
* Blank screen is drawn in canvases sometimes.

There should be a separate bug for making ctx.drawWindow() e10s-compatible - this is nothing we can do without touching the core. So don't worry about it until that's fixed :) If there's no such bug yet we should file one - couldn't find it so far, we should maybe talk to felipe about that.

We'll not work on this as e10s is not an active goal anymore.
