This method is hooked up to model's post_init signal to update dimensions after instantiating a model instance. However, dimensions won't be updated if the dimensions fields are already populated. This avoids unnecessary recalculation when loading an object from the database. Dimensions can be forced to update with force=True, which is how ImageFileDescriptor.__set__ calls this method.
