fromPointToLatLng	fromPointToLatLng(pixel[, noWrap]) Parameters:  pixel:  Point noWrap:  boolean optional Return Value:  LatLng optional This interface specifies a function which implements translation from world coordinates on a map projection to LatLng values. The Maps API calls this method when it needs to translate actions on screen to positions on the map.
