When I turn off my extended desktop, the applications that were on the removed screen are "lost", since they position are not updated.

I have to maximize/minimize to get them back.

I've took a quick look at the code, Workspace::desktopResized is not propagating the event (as far as I can see), so the windows are not notified in any way.

Reproducible: Didn't try

Steps to Reproduce:
xrandr --output LVDS1 --mode 1280x800 --output HDMI1 --mode 1680x1050 --left-of 
Move a window to the HDMI1 screen
xrandr --output HDMI1 --off

Actual Results:  
Some windows are "lost" in the old geometry

Expected Results:  
The windows should be moved and to an available position and resized if needed.
