Ecore_Evas (Wayland): Be sure to unregister the ecore_evas (wrt input 

events).
Add big fat NB wrt potential 'hack' (works around screen garbage on
resize).
Add evas damage rectangle on resize.
Do surface_damage before surface_attach.
Prevent compositor crash on resize by checking width/height <= 0.
Don't do a resize of the ecore_evas unless the event matches.
