Do not update geoLeftBound in Declarative Polygon updateSourcePoints
The left bound of map items is now precomputed when the data is set
(setPath/addCoordinate/etc.).
Updating the left bound of a polyline or polygon every time that
the source points have to be updated (that is projected to screen) is
therefore to be avoided.
