QRCodeWidget ignores the barFillColor parameter

Hi,

needing to draw a QRCode painted in white on a dark background, I see that the
method QRCodeWidget.add() ignores the color passed as "barFillColor". I had to
change it like below (see comment "# LG: "):

    def draw(self):
        self.qr.make()

        g = Group()

        color = self.barFillColor
        border = self.barBorder
        width = self.barWidth
        height = self.barHeight
        x = self.x
        y = self.y

        g.add(SRect(x, y, width, height, fillColor=None))

        moduleCount = self.qr.getModuleCount()
        minwh = float(min(width, height))
        boxsize = minwh / (moduleCount + border * 2.0)
        offsetX = x + (width - minwh) / 2.0
        offsetY = y + (minwh - height) / 2.0

        for r, row in enumerate(self.qr.modules):
            row = map(bool, row)
            c = 0
            for t, tt in itertools.groupby(row):
                isDark = t
                count = len(list(tt))
                if isDark:
                    x = (c + border) * boxsize
                    y = (r + border + 1) * boxsize
                    # LG: actually use the specified barFillColor
                    s = SRect(offsetX + x, offsetY + height - y, count * boxsize, boxsize,
                              fillColor=color)
                    g.add(s)
                c += count

        return g

Does this sound right?

thanks&bye, lele.
