If you need to make OpenGL calls without having an active window (like in a thread), you can use an instance of this class to get a valid context.
Having a valid context is necessary for every OpenGL call.
Note that a context is only active in its current thread, if you create a new thread it will have no valid context by default.
To use a Context instance, just construct it and let it live as long as you need a valid context. No explicit activation is needed, all it has to do is to exist. Its destructor will take care of deactivating and freeing all the attached resources.
