Fix margins for right-to-left mode
The behaviour for considering left and right margins was inconsistent
in views with a right to left layout; these values were reversed for
extent calculations but not for general positioning. With this change
the left and right margins are never reversed in a right-to-left layout,
so minXExtent and maxXExtent calculations always use startMargin
and endMargin respectively, regardless of layout direction.
Also fixes calculation of endOffset in trackedPositionChanged() when
in horizontal orientation.
