I don't understand the question. Why would the model care about
preferred/minimum size?

The minimum size is known for simple cases like the gates. They are 17x17
pixels of something like that.
If the size is not known, for example a label, then you will have other
problems anyway. The use may first resize the label, then increase that
label's text, causing its desired size to grow. I think the solution is to
handle this in the layout, not in the model. So, an XYLayout might verify
that a given constraint does not size the figure smaller than it's minimum
size, and if it does, it would correct this. The size in the model would
still be smaller than the figure's minimum size, but this probably doesn't
matter.
