Select the nearest thumb when thumbs overlap #188

Issue In a RangeBar, when thumb target zones overlap, there's always the left thumb selected. This results in an unpleasant user experience.

Solution Simple: when a touch-down event has an x offset included in both target zones, check which thumb is nearer to the touch's x.
