Thanx for the extra info and fixes guys

What about scrolling, can I render with a starting pixel of (-10, -50)?
Yep that's perfectly ok in OpenGL.

I personally think that SDL is great for window management and also input management. The new classes in v1.0 make it even easier to use both.
Yep, I use SDL for just about everything in my projects, window management, file loading, input, etc, But I just like to do my own OpenGL for rendering .
