new checkbox for binding window layouts in DnD display
Currently, the window layouts (e.g. axial, ortho, 3H) are bound when the geometry is bound.
However, the binding the geometry and the layout are two independent feature, any of them is meaningful without the other.
Remove the "none" checkbox.
Provide a "layout" checkbox that controls the layout binding only.
Change the current behaviour of the "geometry" checkbox to control the binding of only the geometry, not the layout.
