Confortable Client Side is a problem, one solution to this is extend the map 
over the reverse wraping side over 2*max.?size , and assure the refrech of all 
tiles of the
 viewable orbit(all images) of the normal map for all unite moved. 
the keyboard control rest a problem, at last 2 viewable image are present but 
reversed, 
we need probably a spot to determine the keyboard control.
