FinishDrag
Called to signify the user just finished dragging the panel
This handler is called after the user has dragged the plugin display panel to a new position. This handler is called after any drag action, including one that doesn't move the panel (ie: drag left one pixel, drag right one pixel produces no movement but does fire the handler). You should use this handler for any code that needs to act on the position of the display panel. You may use the panel functions to get the current (new) position of the display panel.
