gdk透明贴图好像有点麻烦（以前 Win32 API 用得是 TransparentBlt）

菜单采用GtkUIManager，可以看demo：/usr/share/gtk-2.0/demo/ui_manager.c的透明贴图：

void pixbuf_transparent(GdkPixbuf *dst, const GdkPixbuf *src, gint dstx, gint dsty, guint transcolor)
{
    guchar r = (transcolor & 0xFF0000) >> 16;
    guchar g = (transcolor & 0x00FF00) >> 8;
    guchar b = transcolor & 0x0000FF;
    guchar *p = gdk_pixbuf_get_pixels(dst),
           *q = gdk_pixbuf_get_pixels(src);
    int d = gdk_pixbuf_get_n_channels(src),
        dd = gdk_pixbuf_get_rowstride(src),
        d2 = gdk_pixbuf_get_n_channels(dst),
        dd2 = gdk_pixbuf_get_rowstride(dst),
        w = gdk_pixbuf_get_width(src),
        h = gdk_pixbuf_get_height(src);
    for (int y = 0; y < h; ++y)
        for (int x = 0; x < w; ++x)
        {
            guchar *pp = p + (dsty+y) * dd2 + (dstx+x) * d2;
            guchar *qq = q + y * dd + x * d;
            if (qq[0] != r || qq[1] != g || qq[2] != b)
                pp[0] = qq[0], pp[1] = qq[1], pp[2] = qq[2];
        }
}
