When changing the content of a QWizardPage dynamically at runtime (ex: add/remove or hide/show a widget in the current QWizardPage layout), the window of the QWizard may get resized (by the user) so small than the content of the QWizardPage is not completely visible anymore.

The QWizard window should not accept to be resized smaller than the minimum size hint of its content; whatever happened - at runtime - to the widgets composing the QWizardPage beeing displayed.

Suggested patch attached.
