Martijn Berger 86d2765ebe Interface get rid of some quadstrips in favor of trianglestrips 
If we ever want OpenGL 3.2 core context quadstrips need to go anyway and while there is much more things that need to be done this is something that can be tackled without any mayor surgery.
And without losing any kind of compatibility with ancient GL.
