Rotate GUI texture around 2 different points

Questions & Answers
1

I have a couple of textures - images of stopwatch hands - that I would like to rotate within the same script.

I am using the RotateAroundPivot function to draw the stopwatch hand at the correct angle, and this works fine as long as I only call it the drawLeftStopwatch() or drawRightStopwatch() individually.

However if I include both of these functions in my code, the pivot on the second stopwatch hand appears in a completely different place to what I expect, and the hand does a kind of loop-within-a-loop. The first RotateAroundPivot is incluencing the second RotateAroundPivot in some way.

Is there a way of separating the 2 GUI groups so that the first does not influence the second’s RotateAroundPivot, within the same OnGUI function?

var _stopwatchHand: Texture;
var _rotationAngle = 0;

function Update(){
    _rotationAngle += 5;
}

function OnGUI(){
    // Both of these work individually, but not together
    drawLeftStopwatch();
    drawRightStopwatch();
}

function drawLeftStopwatch(){

    GUI.BeginGroup(Rect(0,0,Screen.width, Screen.height));
    GUIUtility.RotateAroundPivot(_rotationAngle , Vector2(150, 150));
    GUI.DrawTexture(new Rect(300, 300, 128, 128), _stopwatchHand);
    GUI.EndGroup();
}

function drawRightStopwatch(){

    GUI.BeginGroup(Rect(0,0,Screen.width, Screen.height));
    GUIUtility.RotateAroundPivot(_rotationAngle , Vector2(750, 750));
    GUI.DrawTexture(new Rect(900, 900, 128, 128), _stopwatchHand);
    GUI.EndGroup();
}

Save and restore the GUI matrix around the RotateAroundPivot call:

 var mat = GUI.matrix;
 GUIUtility.RotateAroundPivot(_rotationAngle , Vector2(150, 150));
 GUI.DrawTexture(new Rect(300, 300, 128, 128), _stopwatchHand);dPivot(,);
 GUI.matrix = mat;
