Pass the correct object to image load callbacks.

Browse Source 
Previously, the image object was passed on to onTileLoad regardless
if it loaded successfully or not. In case an image failed to load,
this would result in trying to draw a non-existing image onto the
canvas, which (at least in Firefox) throws a DOM exception and results
in the drawer being stuck mid-update.
