Implement a mostly working InfoBubble with a shim BookmarkBubble.

This ended up being implemented as a toplevel instead of a popup, to handle
things like virtual desktop switching.  I imagine there are some other problems
we might hit, like the window getting decorated, etc.  Although I think the
shape mask might prevent decorations from being visible.  This is not pixel
perfect with Windows, since we're not anti-aliasing the frame border.
