    The `grip` pose is used to render an object held in the user's hand.  It's positioned at
    the surface of the palm.  The X axis of the grip orientation is perpendicular to the palm,
    pointing away from the left palm or into the right palm.  If you imagine the hand holding a
    stick, the Z axis will be parallel to the stick.

    The `point` pose is used to aim or point at objects.  It's usually positioned slightly in front
    of the hand or controller, and is oriented so the -Z axis points in a natural forward direction.

    The `pinch` pose is a stable point between the thumb and index finger on a hand, or a point
    slightly in front of a controller.  The -Z axis will point forward, away from the hand.  It's
    good for precise, close-range interaction.

    The `poke` pose is a position located at the tip of the index finger, or a point slightly in
    front of a controller.  The -Z axis will point forward out of the tip of the finger, the +Y axis
    will be perpendicular to the fingernail.

    These "hand pose devices" do not report any button input with e.g. `lovr.headset.isDown`.  The
    main `hand/left` and `hand/right` devices should be used for buttons and haptics.
