Submit a vertex.

In OpenGL this matches glVertex3f(v.x,v.y,v.z); on other graphics APIs the same functionality is emulated.

This function can only be called between GL.Begin and GL.End functions.

	// Draws a line from the bottom right
	// to the top left of the Screen
	// Using GL.Vertex
	var mat : Material;
	function OnPostRender() {
		if (!mat) {
			Debug.LogError("Please Assign a material on the inspector");
			return;
		}
		GL.PushMatrix();
		mat.SetPass(0);
		GL.LoadOrtho();
		GL.Begin(GL.LINES);
		GL.Vertex(Vector3(1,0,0));
		GL.Vertex(Vector3(0,1,0));
		GL.End();
		GL.PopMatrix();
	}
