Great It's good to know that the GL1 target works on Intel graphic cards.

It would be useful to know where it crashes, then we could trap it at that point (and throw an exception)

Maybe we should default to GL1 for the examples that only require OpenGL 1.3. ?

It's a difficult one to answer. Since the GL target (OpenGL V2.0 and above) perfoms a lot better on NVidia and ATI cards.
