    ''''UNUSED - done in XSLT
    Convert Eden WKT polygon (and eventually circle) representation to
    CAP format and provide them in the rendered s3xml.
    Not all internal formats have a parallel in CAP, but an effort is made
    to provide a resonable substitute:
    Polygons are supported.
    Circles that were read in from CAP (and thus carry the original CAP
    circle data) are supported.
    Multipolygons are currently rendered as their bounding box.
    Points are rendered as zero radius circles.
    Latitude and longitude in CAP are expressed as signed decimal values in
    coordinate pairs:
    latitude,longitude
    The circle text consists of:
    latitude,longitude radius
    where the radius is in km.
    Polygon text consists of a space separated sequence of at least 4
    coordinate pairs where the first and last are the same.
    lat1,lon1 lat2,lon2 lat3,lon3 ... lat1,lon1'
