The focus signal is used to let the focus switch between elements in a way as easy as possible. FIXME: be more verbose here
At the beginning, there is no focus. So, once the focus enters the view, it emits the 'focus' signal on the root, FIXME: continue here
If there is a focus, we can easily find out which element the focus has, the we can move up the canvas tree and find the next item to be focused.
