    /// <summary>
    /// The SetGraphicsMode function sets the graphics mode for the specified device context.
    /// </summary>
    /// <param name="hdc">Device Context to operate on</param>
    /// <param name="iMode">The graphics mode. This parameter can be one of the following values.
    /// Value    Meaning GM_COMPATIBLE Sets the graphics mode that is compatible with 16-bit Windows.
    /// This is the default mode. If this value is specified, the application can only modify the
    /// world-to-device transform by calling functions that set window and viewport extents and
    /// origins, but not by using SetWorldTransform or ModifyWorldTransform; calls to those functions
    ///  will fail. Examples of functions that set window and viewport extents and origins are
    /// SetViewportExtEx and SetWindowExtEx.
    /// GM_ADVANCED Sets the advanced graphics mode that allows world transformations.
    /// This value must be specified if the application will set or modify the world transformation
    /// for the specified device context. In this mode all graphics, including text output, fully conform
    /// to the world-to-device transformation specified in the device context.</param>
    /// <returns>If the function succeeds, the return value is the old graphics mode.
    /// If the function fails, the return value is zero. </returns>
