This class is used by SWTEventDispatcher as support to display Figure tooltips on a mouse hover event. Tooltips are drawn directly below the cursor unless the display does not allow, in which case the tooltip will be drawn directly above the cursor. Tooltips will be displayed with a LineBorder. The background of the tooltips will be the standard SWT tooltipBackground color unless the Figure's tooltip has set its own background.
