Message:

Tile.Image should register for error events with respect to tile loading
events -- this means that if an image fails to load, it will still trigger
a loadend event, and the layer will eventually be in a state where it is no
longer waiting to load. Thanks to Andreas for the investigation! (Closes #842)
