Next up, add morphing 😎

add morphing

That's worthy of a separate lib :)

You already have gfxmorph 🤣

This is nearly done, but the ux needs some thought and work. I'm thinking something like this:

• User clicks points to create the polygon. Optionally start with existing polygon.
• Once created, vertices can be dragged.
• Clicking on an edge will split it in two, creating an extra vertex.
• Double-clicking on inside the polygon will delete and let the user create a new polygon.

All this sounds good to me!

I think this should be explicitly called, or via imgui right click menu. Or clicking on the fill area selects the polygon and presing the "Del" key deletes it.
