[OpenLayers-Users] Write a KML file in proper projection.

[bartvde at osgis.nl]

Define internalProjection and externalProjection on your format:

    /**
     * APIProperty: externalProjection
     * {<OpenLayers.Projection>} When passed a externalProjection and
     *     internalProjection, the format will reproject the geometries it
     *     reads or writes. The externalProjection is the projection used by
     *     the content which is passed into read or which comes out of write.
     *     In order to reproject, a projection transformation function for
the
     *     specified projections must be available. This support may be
     *     provided via proj4js or via a custom transformation function. See
     *     {<OpenLayers.Projection.addTransform>} for more information on
     *     custom transformations.
     */
    externalProjection: null,
