Subject: several changes towards 5.3, XINERAMA is disabled by default,
 introduced usegrab Bool for grabbing the server during mouse-based
 resizals/movements (disabled by default), continued debugging tile() with
 resizehints == True and a lot of terminals supporting resizehints, still no
 optimal solution, I need to think about it, considering recursive algorithm
 for the space optimization
