messageTray: use a "hot corner" to summon the tray

Browse Source 
Instead of leaving the tray covering the whole last pixel row when it's
hidden, hide it completely. This avoids mouse events not being delivered to
application windows on the last pixel row.

To summon the tray we use a single reactive pixel on the corner.
