Pixelator example: incorrect sentences about constructor

The documentation for the "Pixelator Example", in the "ImageModel Class Definition" section, states:

"For convenience, the image to be used is passed in the constructor."

But looking at the example code, the constructor has the following definition:

ImageModel(QObject *parent = 0);

And there exists a setImage() method, so I'd say that the image is not passed in the constructor. That sentence should be removed from the documentation.
