Currently the collision detection for clicking on a surface edge uses a circle at the edge.
This should be replaced with a rectangle that extends the width of the surface but not the length.
This will make clicking feel easy, allow clicking on the whole area of the surface edge and also stop clicking both connected edges.
A simple AABB is not sufficient because surfaces can be at any angle.
