Version Mismatch #176

Hi,

It am not sure whether the following snippet give me the correct version of my openGL

`window = GLFW.CreateWindow(10, 10, "OpenGL Example")

Make the window's context current

GLFW.HideWindow(window)
GLFW.MakeContextCurrent(window)
glversion = unsafe_string(glGetString(GL_VERSION))`

I am pretty confident that the version of the openGL on my mac book is 4.1 but somehow the above snippet give me 2.4. What could be the possible source of this disagreement?

Best,

You probably need to pass context hints before creating the window. Some platforms return older versions of OpenGL to remain backwards compatible with older applications.

Thank you for the clarification. Indeed, that is precisely what I need to do.
