HdyViewSwitcher: Show the window title
When @zbrown submitted the view switcher, it had a third mode which was the window's title, but I wasn't happy about it as that title had to be set manually. Instead, I introduced
HdySqueezer to handle that externally.
I now feel I was wrong and the view switcher should by default shrink to display the window's title, making the squeezer useless for that, but at the condition the window title is automatically retrieved like
GtkHeaderBar does. Of course, the
HdyViewSwitcherBar shouldn't show the window's title.
