Retrieves a new AutomationElement object for the user interface (UI) item at specified point on the desktop.
Assembly: UIAutomationClient (in UIAutomationClient.dll)
returns the element in the logical tree that is closest to the root element.
If your client application might try to find elements in its own user interface, you must make all UI Automation calls on a separate thread.
Although the point is within the bounding rectangle of the returned AutomationElement, it is not necessarily on a clickable part of the control. For example, a round button might not be clickable near one of the corners of its bounding rectangle.
