:Array.<THREE.Vector3>

refPoints

Stores the reference positions required for the action.

For a simple move, this is just the start point [0] and the drag point [1]. For a rotation, it is the center point [0], the reference direction [1] and the drag direction [2]. You can add any extra points your action needs within the subclass constructor.

setupStages

The progress stage at which setup finishes and dragging begins.

Setup stages display a detached cursor and are used to set the reference positions prior to actual dragging. During these stages, the user can click anywhere in the canvas and the cursor will move to that spot, and snapping should include the selected element. After the setup stages, when the user is dragging the selected element around, it should be excluded from snap detection.
