func (*App) EventPos 

func (a *App) EventPos(e js.Value) image.Point

EventPos returns the appropriate position for the given event, multiplying the x and y components by the device pixel ratio so that they line up correctly with the canvas.

func (*App) EventPosFor 

func (a *App) EventPosFor(x, y js.Value) image.Point

EventPosFor transforms the given position by multiplying the x and y components by the device pixel ratio so that they line up correctly with the canvas.
