NAME
        DrawBorder -- draw the specified border structure into a rastport.

    SYNOPSIS
        DrawBorder( rastport, border, leftoffset, topoffset )
                    A0        A1      D0          D1

        VOID DrawBorder( struct rastport *, struct border *, word, word );

    FUNCTION
        First, sets up the draw mode and pens in the rastport according to the
        arguments of the border structure.  then, draws the vectors of
        the border argument into the rastport, offset by the left and top
        offsets.

        As with all graphics rendering routines, the border will be clipped to
        to the boundaries of the RastPort's layer, if it exists.  This is
        the case with window RastPorts.

        This routine will draw all borders in the NULL-terminated list linked
        by the NextBorder field of the border argument.

    INPUTS
        rastport = pointer to the rastport to receive the border rendering
        border = pointer to a border structure
        LeftOffset = the offset to be added to each vector's x coordinate
        TopOffset = the offset to be added to each vector's y coordinate

    RESULT
        None
