+This variable controls the maximum number of hexes in a map, that can be parsed by an event.
+It was set to 1024 before and for larger maps this could become a problem. So it is raised to 
+65536 now, which can feature a map of size 256*256 (maps really shouldn't be bigger than that :-).
+This constant also controls the maximum number of loops for a WML while loop (hence its name).
+If this is felt to be too high now, we must split it into two constants, but i don't feel the need
+at the moment.
