/// The [`Picture`][crate::Picture] widget displays a [`gdk::Paintable`][crate::gdk::Paintable].
///
/// 
///
/// 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
/// [`gdk::Texture::from_file()`][crate::gdk::Texture::from_file()], 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.
///
/// ## CSS nodes
///
/// [`Picture`][crate::Picture] has a single CSS node with the name `picture`.
///
/// ## Accessibility
///
/// [`Picture`][crate::Picture] uses the `GTK_ACCESSIBLE_ROLE_IMG` role.
