    /// Many convenience functions are provided to make pictures simple to use.
    /// For example, if you want to load an image from a file, and then display
    /// it, there’s a convenience function to do this:
    ///
    /// **⚠️ The following code is in c ⚠️**
    ///
    /// ```c
    /// GtkWidget *widget = gtk_picture_new_for_filename ("myfile.png");
    /// ```
    ///
    /// If the file isn’t loaded successfully, the picture will contain a
    /// “broken image” icon similar to that used in many web browsers.
    /// If you want to handle errors in loading the file yourself,
    /// for example by displaying an error message, then load the image with
    /// and image loading framework such as libglycin, then create the [`Picture`][crate::Picture]
    /// with [`for_paintable()`][Self::for_paintable()].
    ///
    /// Sometimes an application will want to avoid depending on external data
    /// files, such as image files. See the documentation of `GResource` for details.
    /// In this case, [`for_resource()`][Self::for_resource()] and
    /// [`set_resource()`][Self::set_resource()] should be used.
    ///
    /// [`Picture`][crate::Picture] displays an image at its natural size. See [`Image`][crate::Image]
    /// if you want to display a fixed-size image, such as an icon.
    ///
    /// ## Sizing the paintable
    ///
    /// You can influence how the paintable is displayed inside the [`Picture`][crate::Picture]
    /// by changing [`content-fit`][struct@crate::Picture#content-fit]. See [`ContentFit`][crate::ContentFit]
    /// for details. [`can-shrink`][struct@crate::Picture#can-shrink] can be unset to make sure
    /// that paintables are never made smaller than their ideal size - but
    /// be careful if you do not know the size of the paintable in use (like
    /// when displaying user-loaded images). This can easily cause the picture to
    /// grow larger than the screen. And [`halign`][struct@crate::Widget#halign] and
    /// [`valign`][struct@crate::Widget#valign] can be used to make sure the paintable doesn't
    /// fill all available space but is instead displayed at its original size.
