Description
Crop mode in VR with a volume in tilted slab style does not consistently choose which face of the slab to move. Sometimes it moves the face being pointed to with the controller and sometimes the other face.

Fixed in daily build and 1.7 release candidates dated Nov 22, 2023.
The crop code was looking at the camera direction instead of the hand-controller pointing direction. That makes sense on the desktop display, but in VR I think we want to choose the front or back of the slab based on the hand-controller pointing direction not the view direction. So I fixed it in VR so the slab face is chosen based on the hand controller pointing direction. So if you point at the front face from the front it moves the front face, and if you point at the back face from the back it moves the back face. This can be a bit cumbersome to move the back face (the one farthest from view) because it suggests you should reach behind the slab and point back at it. But in fact it is only the direction of pointing that matters, while the position of the hand-controller is ignored. So you can have the hand-controller in front of the front face of the slab put point away from the slab and it will move the back face. What matters is if you look at the outward facing normal vectors from front and back slab faces, the hand-controller moves the face whose normal points opposite the hand-controller pointing direction. This makes it easy to move either slab face from any position.
Pointing from in front of the slab face you want to move at the slab face is pretty intuitive. The one aspect that may not be so intuitive is that if you want to move the back slab face you might think you can poke the hand controller through the slab to reach the back face and move it. But it doesn't work that way. Given that the slab may be large and out of arm's reach I think the current behavior where only the pointing direction of the hand-controller matters is probably best.
