- updated the Distance Tool such that the right click of the mouse will cancel the tool unless it was a panning move

- modified the PlotCanvasLegacy to decide if there is a mouse drag based on the distance between the press event position and the release event position. If the distance is smaller than a delta distance then it is not a drag move.
