Support Option-resizing lines

The help text below the toolbar when linear elements are dragged for resizing is wrong:

It mentions “alt” can be used, but it cannot be.

Also the text is slightly cut off, notice the p in proportions:

There are some related issues around the repo to this. Should we allow the alt-scaling for arrows? Should we just have the same resizing logic for arrows as we have for rectangles?

One thing I would super like, but might need more changes, is if alt+dragging corner created a new line with the other points in the same position, like this:

Right now I always have to copy, paste, then shift both points (or the linear element and the second point). (but if we wanted to make this consistent with other shapes we would have to figure out separate modifier key combos)

What do you mean by alt text, and what’s wrong exactly?

Even if we don’t support Alt+resizing lines, I’m not sure if making the Alt+resize behavior be completely different between other shapes and lines, that would be confusing.
