ओपनजीएल संदर्भ निर्माण।

एक मूल विंडो बनाना

यह ट्यूटोरियल मानता है कि आपके पास पहले से ही सभी आवश्यक पुस्तकालयों और हेडर के साथ काम करने वाला ओपनजीएल वातावरण है।

//Window hints are used to manipulate the behavior of later created windows
//As the name suggests, they are only hints, not hard constraints, which means
//that there is no guarantee that they will take effect.
//GLFW_RESIZABLE controls if the window should be scalable by the user
//GLFW_SAMPLES specifies how many samples there should be used for MSAA
//GLFW_VISIBLE specifies if the window should be shown after creation. If false, it
//             can later be shown using glfwShowWindow()
//For additional windowhints please consult the documentation
