Sample a position layer (default P_lig) with a pick knob, then spawn Card2, Card3D, Axis2, or Light2 at that translate.
Sample 2 Node shuffles a position channel (defaults to P_lig), exposes a 3D pick sample, and provides buttons that create Card2, Card3D, Axis2, or Light2 in the root with translate set to the sampled value.
Convenience for 'sample this pixel's P and drop a card/light there' without hand-copying values from a Position pass.
