How do you specify that an input image is optional?

Good question. We dont have a mechanism for this yet.
I think we even need to improve the way that data
is passed to the subclasses of point op (say) before
we address this.
Well, it seems to me that a mask op should be an optional thing. So, I
suppose, to add a mask op, this needs to be done first.
