OpenGL coordinates start from the bottom left, instead of the usual top-left 
screen coordinates. So we usually must multiply the Y axis by -1.

The problem is that if you multiply one too many times or one too few, 
everything is reversed, like you saw. It's possible that something inside 
Visual Studio is interfering.
