Changing texture ignored.

[yuichi sugimura]

In setting-default-background-color usage,
changing texture is completely ignored.

The reason is that image cache is not flushed in
setTextureURL(URL) method.

    public void setTextureURL(URL url)
    {
        if (!isTexture() || url == null)
            return;
        m_textureURL = url;
        m_dirty = true;
                m_image = null; // You should also do this
    }   //  setTextureURL

Fixing this way makes getTextureImage() method works well.

Really nice Look and Feel, I like it!
