[cairo] Cairo documentation example error

[Fabien Costantini]

In
  http://www.cairographics.org/manual/cairo-Paths.html#cairo-arc

In the ellipse example:

  Replace:
cairo_save (cr);
cairo_translate (x + width / 2., y + height / 2.);
cairo_scale (1. / (height / 2.), 1. / (width / 2.));
cairo_arc (cr, 0., 0., 1., 0., 2 * M_PI);
cairo_restore (cr);

  By:

cairo_save (cr);
cairo_translate (cr, x + width / 2., y + height / 2.);
cairo_scale (cr, 1. / (height / 2.), 1. / (width / 2.));
cairo_arc (cr, 0., 0., 1., 0., 2 * M_PI);
cairo_restore (cr);
Hope this will help,
Fabien

  ^^^^^^^^^^^^^^^

It shouldn't happen with 1.2.  Let me know if it does.
