Comment:

 Okay. Destroy is too late, so we add an 'unload' method to the tile.
 Anyone wanting to get events when a tile is about to be destroyed if it is
 still loading has the requirement of calling tile.unload() on the tile:
 This will cause the tile to report an 'unload' event if it is still
 loading at the time the method is called. The layer should register for an
 unload event, and use that to decrement the count. (This also fixes
 another bug in the previous patch, which was that you could get a
 numTilesLoading of -1.) Also, unregister our events. (Which is what made
 me think it was working before, cause I wasn't cleaning up after myself.)
 Also, do it for the WFS layer too, since it suffers the same problem.

 I've confirmed that when I resize the map with a single untiled layer, I'm
 getting load start/end events that match up one to one. Bart, please try
 this one when you get a chance.
