RT-25174: Region doesn't play nice with mouse bounds picking in certain circumstances
Summary: Partial fix. This addresses the Region side of the problem by implementing pick semantics consistent with a rounded rectangle. The rest of the fix will require a change in the VirtualFlow to handle the problem of which rows are above/beneath the others.
