Bug 203403

I'm using Scene2Image#getSceneImageMapCoordinates on its own, but it doesn't work when scale isn't set. The scale can't be set, so I've had to add a setScale method. 

I'm using this to generate an html area map on it's own, as I"m generating the image separately. 

My usage looks like this:

  Scene2Image s = new Scene2Image( this, null );
  s.setScale( 1 );
  List<WidgetPolygonalCoordinates> coords = s.getSceneImageMapCoordinates( 0 );

Can this be made work? Could add a setScale method, or have getSceneImageMapCoordinates take a scale parameter or even just make scale protected, rather than private, so it can be called by a subclass.

I'm happy to provide a patch with whatever approach would be deemed acceptable.

Thank you.
