+/// \class sf::ContextSettings
+///
+/// ContextSettings allows to define several advanced settings
+/// of the OpenGL context attached to a window. All these
+/// settings have no impact on the regular SFML rendering
+/// (graphics module), so you may need to use this structure
+/// only if you're using SFML as a windowing system for
+/// custom OpenGL rendering.
+///
+/// The DepthBits and StencilBits members define the number
+/// of bits per pixel requested for the (respectively) depth
+/// and stencil buffers.
+///
+/// AntialiasingLevel represents the requested number of
+/// multisampling levels for anti-aliasing.
+///
+/// MajorVersion and MinorVersion define the version of the
+/// OpenGL context that you want. Only versions greater or
+/// equal to 3.0 are relevant; versions lesser than 3.0 are
+/// all handled the same way (i.e. you can use any version
+/// < 3.0 if you don't want an OpenGL 3 context).
+///
+/// Please note that these values are only a hint.
+/// No failure will be reported if one or more of these values
+/// are not supported by the system; instead, SFML will try to
+/// find the closest valid match. You can then retrieve the
+/// settings that the window actually used to create its context,
+/// with Window::GetSettings().
