    /// A widget that allows to bypass gsk rendering for its child by passing the content
    /// directly to the compositor.
    ///
    /// Graphics offload is an optimization to reduce overhead and battery use that is
    /// most useful for video content. It only works on some platforms and in certain
    /// situations. GTK will automatically fall back to normal rendering if it doesn't.
    ///
    /// Graphics offload is most efficient if there are no controls drawn on top of the
    /// video content.
    ///
    /// You should consider using graphics offload for your main widget if it shows
    /// frequently changing content (such as a video, or a VM display) and you provide
    /// the content in the form of dmabuf textures (see `Gdk::DmabufTextureBuilder`),
    /// in particular if it may be fullscreen.
    ///
    /// Numerous factors can prohibit graphics offload:
    ///
    /// - Unsupported platforms. Currently, graphics offload only works on Linux with Wayland.
    ///
    /// - Clipping, such as rounded corners that cause the video content to not be rectangular
    ///
    /// - Unsupported dmabuf formats (see [`DisplayExtManual::dmabuf_formats()`][crate::gdk::prelude::DisplayExtManual::dmabuf_formats()])
    ///
    /// - Translucent video content (content with an alpha channel, even if it isn't used)
    ///
    /// - Transforms that are more complex than translations and scales
    ///
    /// - Filters such as opacity, grayscale or similar
    ///
    /// To investigate problems related graphics offload, GTK offers debug flags to print
    /// out information about graphics offload and dmabuf use:
    ///
    ///     GDK_DEBUG=offload
    ///     GDK_DEBUG=dmabuf
