/*NO DOuBLE RELOAD
...has reloaded once when timeoutResize submits again--does it have to submit - can the first map be the right size??

OLD:
then
myLoad->windowResize->resizeMapComponents->nlwisResizeElement
		windowResize-timeoutResize-goServerMapRefresh-submitMapResize->
resize event-one gotevent, one myload

the rub: can't resize until elms created already
alternately--get size in login; have it make the map right in first place rather than resizing --> MapSize widget
