panel: Allow restoring maximized/tiled windows by touch
Maximized and tiled windows can be restored with a drag gesture,
not only from their titlebars, but also from any non-reactive
parts of the top bar above the window. Currently this only works
for actual pointer devices, extend the behavior to handle touch
as well.
