This makes the edit mode drawing for the new curves data more similar to the old edit mode. Specifically, it draws the evaluated curves now instead of just a poly curve. Furthermore, it now draws bezier handles as well as a separate control curve for nurbs curves. Pull Request: https://projects.blender.org/blender/blender/pulls/119053
