Polygon Inner rings orientation

[Montago]

This change orients inner rings (holes) in polygons correctly (CCW)

This fixed the problem for Polygons but not for MultiPolygons. The (new) example of a MultiPolygons with a hole from Wikipedia still does not render correctly.

MULTIPOLYGON (((40 40, 20 45, 45 30, 40 40)), ((20 35, 10 30, 10 10, 30 5, 45 20, 20 35), (30 20, 20 15, 20 25, 30 20)))

There is one small change to get this to work for MultiPolygons; you have to check for the Polygon type.

// Orient inner rings correctly
if (polygonIsClockwise(c[j]) && this.type == 'polygon') {
  verts.reverse();
}

The deconstruct() method in wicket-gmaps3.js needs the same kind of fix, but the code is more complicated. One of the things that needs to be fixed is the determination of multiFlag; the determination of whether or not a google.maps.Polygon instance is a Polygon or MultiPolygon.

It should be very easy to find out if Google maps contain multi polygons or not by looking at the direction they are made.. eg, if two polygons are CW => multi
If one polygon is CW and the rest are CCW, then its a polygon with holes
