3D OBB with pointer-based manipulation features.
We say "frame" because only the 12 edges of the box are rendered via
bevy_polyline.
Faces of the box can be dragged by the pointer to manipulate the box extents. As the pointer hovers over each face, visual feedback is provided (highlight material).
Depends on [bevy_mod_picking::DefaultPickingPlugins] and
[bevy_polyline::PolylinePlugin].
