/* 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) -- except the anti-aliasing level, 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().
