docs: Override this method if you need custom handler logic. Note that this method can actually be
  called directly for performance reasons, in which case the message will be null
  
  @param bitmap the bitmap returned from the image loader
  @param msg    the handler message; can be null
  @return true if the view was updated with the new image, false if it was discarded
