-
-generalize selector to pick last Nth rather than very last
-        adapt getIdFromPick() with .slice() after filter then map on length-N instead of length-1
-
-selector pickers : pickClass and pickId
-        display result in 3D HUD with rotating objects and selector value
-                ideally themselves also selectable/usable, e.g clone from HUD to bring back "out"
-                         requires extra work as becoming a child will not work, own positionning
-                                should fix that
-                        could compare to world coordinates instead of "just" position attribute
-        add a clear selector function to avoid making the HUD unusable
-
-could also pick via volume, e.g wireframe box
-        start with https://threejs.org/docs/#api/en/math/Box3.containsPoint
-                can iterate with https://threejs.org/docs/#api/en/math/Box3.containsBox
-                consider also https://threejs.org/docs/#api/en/math/Box3.intersectsBox
-
-consider pick then apply, i.e changeColorLastId() but for next Id
-        should be cancealable
