 * Starts a drag.
 * When the drag is started, the UI automatically goes into spring loaded mode. On a successful
 * drop, it is the responsibility of the {@link DropTarget} to exit out of the spring loaded
 * mode. If the drop was cancelled for some reason, the UI will automatically exit out of this mode.
 *
 * @param b The bitmap to display as the drag image.  It will be re-scaled to the
 *          enlarged size.
 * @param originalView The source view (ie. icon, widget etc.) that is being dragged
 *          and which the DragView represents
 * @param dragLayerX The x position in the DragLayer of the left-top of the bitmap.
 * @param dragLayerY The y position in the DragLayer of the left-top of the bitmap.
 * @param source An object representing where the drag originated
 * @param dragInfo The data associated with the object that is being dragged
 * @param dragRegion Coordinates within the bitmap b for the position of item being dragged.
 *          Makes dragging feel more precise, e.g. you can clip out a transparent border
