CloseMode for Begin: draw triangle strip.
If you want to draw something 2D in screen space then
probably you will want to use GL.LoadOrtho or GL.LoadPixelMatrix.
If you want something in "3D", then probably you should consider
using GL.LoadIdentity followed by GL.MultMatrix with the actual
3D transform you want your stuff to be in.
See Also: GL.Begin, GL.End.
