Subject: QNX 6.3 fixes for SDL
Sam, I've added new OpenGL framework for SDL, which appeared in the new QNX version - 6.3. I've leave compatibility with previous QNX versions. And I've moved all GL specific functions to the separate module, like it done for the other platforms.
SDL is now ready for the QNX 6.3 :)
