    buffer: free the tile handler's source unconditionally in dispose()
    
    The code there was probably trying to be smart about reusing stuff,
    but nobody else was ever releasing that reference, so it was clearly a
    leak. If this breaks whatever smart reusing scheme, it needs to handle
    reference counting differently.
