Rectlinear shape update

[yangluo23]

Dear authors,
Thanks for your novel work. Now I have met a problem that I need to update a rectilinear shape polygon. In diffvg, one possible way to represent such polygon is to use path (Line to) primitives, but how should I update such path where there are horizonal and vertical update step constraints for edges?

Have you found any solution for this?

Hi, actually later I just gave up this idea. But for this question, one intuitive way is to control the gradient vector, i.e., MASK one axis's gradient. But the overall performance may need further improvement.

Thanks for the feedback!
I will take a look at it in the coming days.
