Shrinkwrap Constraint: implement projection features from the modifier.
Allow raycasting in two directions and culling front or back faces.
Also implement a new Invert Cull option in both constraint and
modifier that can be used to aim for faces aligned with the project
axis direction when raycasting both ways.
