Ticket #74 (feature request)

Need to add an "antialiasing" property to Stroke objects. If this is True, then the renderer should turn on antialiasing.

Howard had success with the MapServer? renderer like:

        elif ISLDPolygonSymbolizer.providedBy(symbolizer):
            f = symbolizer.fill
            s = symbolizer.stroke
            layerob.transparency = _mapscript.MS_GD_ALPHA

            try:
                if f:
                    styleob.color.setHex(f.color)
                    si = classob.insertStyle(mapscript.styleObj())
                    sty2 = classob.getStyle(si)
                    sty2.symbol = 1
                    try:
                        sty2.size = int(s.width)
                    except AttributeError:
                        pass
                    sty2.outlinecolor.setHex(s.color)
                    sty2.antialias = _mapscript.MS_TRUE
                else:
                    styleob.outlinecolor.setHex(s.color)
                    try:
                        styleob.width = int(s.width)
                    except AttributeError:
                        pass

            except:
                raise
