Sorry if this has been covered elsewhere, I did not see it.

Is the Input's Touch position 'inverted' relative to the screen? The reason I ask is that if I do this:

var touch = Input.GetTouch(0);
if (windowRect.Contains(touch0.position))
{
  .. do something ..
}

where windowRect is set in OnGUI:

windowRect = GUILayout.Window(GetInstanceID(), windowRect, DisplayData, "title");

It will only 'do something' IFF I touch the screen in the 'mirrored' position (up/down aka Y direction). Ex: if my windows is near the top of my screen, it will not detect this containment if I touch near the top (inside the window). But it WILL detect if I touch on the opposite side of the screen (same X, opposite Y).

I must have missed something in the docs? Or is it a bug?

Update: Is this what GUIUtility.ScreenToGUIPoint is for?
