+//
+//			* before: places tooltip to the left of the target node/widget, or to the right in
+//			  the case of RTL scripts like Hebrew and Arabic
+//			* after: places tooltip to the right of the target node/widget, or to the left in
+//			  the case of RTL scripts like Hebrew and Arabic
+//			* above: tooltip goes above target node
+//			* below: tooltip goes below target node
+//
+//		The list is positions is tried, in order, until a position is found where the tooltip fits
+//		within the viewport.
+//
+//		Be careful setting this parameter.  A value of "above" may work fine until the user scrolls
+//		the screen so that there's no room above the target node.   Nodes with drop downs, like
+//		DropDownButton or FilteringSelect, are especially problematic, in that you need to be sure
+//		that the drop down and tooltip don't overlap, even when the viewport is scrolled so that there
+//		is only room below (or above) the target node, but not both.
