Light Rays 0.7 - identity projection and view matrix to render full screen

	// 2a: now that we've got the scene in a texture we're going to apply an
	// effect on it. To apply an effect we need to draw it again now using the
	// mode = 3.
	//
	// note that we use a trick here to draw the rendered scene onto a plane
	// with a width and height of 2. (-1 to 1). which are the normalized
	// device coordinates. Basically what we do here is drawing the captured
	// scene (captured with fbo) onto a plane which is almost the same size
	// of the window. I say almost because we use 1.9 here (instead of 2).
