Saves both projection and modelview matrices to the matrix stack.
Changing modelview or projection matrices overrides current camera's parameters.
These matrices can be saved and restored using GL.PushMatrix and GL.PopMatrix.

// Draw a yellow line from the botton left to the
// top right of the screen
var mat : Material;
function OnPostRender() {
if (!mat) {
Debug.LogError("Please Assign a material on the inspector");
return;
}
GL.PushMatrix(); // Save the current state
mat.SetPass(0);
GL.LoadPixelMatrix();
GL.Color(Color.yellow);
GL.Begin(GL.LINES);
GL.Vertex3(0,0,0);
GL.Vertex3(Screen.width, Screen.height,0);
GL.End();
GL.PopMatrix(); // Pop changes.
}
