{Boolean} Set this to true if you don’t want the map center to change while pinching. For example you may want to set preserveCenter to true when the user location is being watched and you want to preserve the user location at the center of the map even if he zooms in or out using pinch. This property’s value can be changed any time on an existing instance. Default is false.
