First cut at Exit Fullscreen bubble on Linux.

First cut at Exit Fullscreen bubble on Linux.

It shows and disappears after 3 seconds.  There is no way to bring it
back.

The following remain to be done:
- Rounding the bottom corners (with a radius of 8, ActAsRoundedWindow
  looks ugly) and make it transparent.
- Slide in/out animation.
- Implement the logic in the Windows version for when to show or hide the
  bubble.  It's pretty complicated and I haven't decided whether to
  port it or to try to share it.

crbug.com/24950 has a patch attached which makes "actual" rounded corners, which
I abandoned because for small radiuses it didn't look any better. It doesn't do
transparency though (or aliased corners). So you probably won't find it useful,
but I thought I'd mention it.

I think when you wrap the parameters, you have to wrap the initializer list

Nope, not yet.  Removed.
