Implement wfh functions

Browse Source 
With only get_preferred_width and get_preferred_height implemented,
we end up calling the GtkBin height_for_width implmementation, which
knows nothing about the margins and paddings that GtkPopover needs.
As a result, a listbox added to a popover was getting cut off
at the bottom.
