Struct Drag 

pub struct Drag {
    pub phase: DragPhase,
    pub location: Point,
    pub translation: Point,
}

Drag info delivered to a shape’s .on_drag handler.

translation is cumulative from where the pointer went down; location is where it is now, in the piece’s own coordinates. The two are not redundant, because Began does not always arrive at the press: a backend whose recognizer has to watch a few events before it calls the gesture a drag (appkit raises Began on the first drag event) reports where it recognized the drag, with the translation from the press already applied. So the press is location - translation, on every backend and in every phase; take the anchor that way rather than from Began’s location, or a gesture measured from the anchor trails the pointer by however far it moved before the recognizer engaged.
