NAME
        AreaEnd -- process table of vectors and ellipses and produce areafill.


   SYNOPSIS
        error = AreaEnd(rp)
          d0            A1

        long areaend( struct rastport * );

   FUNCTION
        Trigger the filling operation.
        process the vector buffer and generate required
        fill into the raster planes. After the fill is complete, reinitialize
        for the next areamove or areaellipse. use the raster set up by
        inittmpras when generating an areafill mask.

   RESULT
        error - zero for success, or -1 if an error occurred anywhere.

   INPUTS
        rp - pointer to a rastport structure which specifies where the filled
             regions will be rendered to.
