From 70197161511b1504a6d6d655a288d2d922938a0f Mon Sep 17 00:00:00 2001

Subject: [PATCH] fullscreenhook: publish the active fullscreen window
Set _DWM_FULLSCREEN on the root window to the selected fullscreen
client, and clear it when the selected client is not fullscreen.
Update the property on focus and fullscreen changes so it remains
correct across tags, monitors, client exits, and multiple fullscreen
clients.
