Method 1. If you use EGeoXml or GeoXml instead of GGeoXml you would be
able to add {polygonoptions{clickable:false}}, in which case all the
clicks drop through to the map.
Method 2: Since you don't appear to be filling the polygon, you could
replace it with a polyline by using a KML <LineString> in which case
only clicks on the line would be intercepted.
Method 3: You could listen for map "addoverlay" events, looking for one
that's an instanceof GPolygon, then make a copy of it with
{clickable:false} and remove the original one. [Be careful not to get
into a loop when you get the "addoverlay" event for your new GPolygon.]
Method 4: You could listen for map "addoverlay" events, looking for one
that's an instanceof GPolygon, then add a "click" listener to that. Your
polygon "click" listener could either perform your user click processing
directly or trigger a map "click" event that would be picked up by your
existing map click listener.
