+/// \class sf::ContextSettings
+/// \ingroup window
+///
+/// ContextSettings allows to define several advanced settings
+/// of the OpenGL context attached to a window. All these
+/// settings with the exception of the compatibility flag
+/// and anti-aliasing level 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).
+///
+/// When requesting a context with a version greater or equal
+/// to 3.2, you have the option of specifying whether the
+/// context should follow the core or compatibility profile
+/// of all newer (>= 3.2) OpenGL specifications. For versions
+/// 3.0 and 3.1 there is only the core profile. By default
+/// a compatibility context is created. You only need to specify
+/// the core flag if you want a core profile context to use with
+/// your own OpenGL rendering.
+/// <b>Warning: The graphics module will not function if you
+/// request a core profile context. Make sure the attributes are
+/// set to Default if you want to use the graphics module.</b>
+///
+/// Setting the debug attribute flag will request a context with
+/// additional debugging features enabled. Depending on the
+/// system, this might be required for advanced OpenGL debugging.
+/// OpenGL debugging is disabled by default.
+///
+/// <b>Special Note for OS X:</b>
+/// Apple only supports choosing between either a legacy context
+/// (OpenGL 2.1) or a core context (OpenGL version depends on the
+/// operating system version but is at least 3.2). Compatibility
+/// contexts are not supported. Further information is available on the
+/// <a href="https://developer.apple.com/opengl/capabilities/index.html">
+/// OpenGL Capabilities Tables</a> page. OS X also currently does
+/// not support debug contexts.
+///
+/// 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().
