Sets the position of the user control that is specified by userControlId.

intArray holds the x,y coordinates of the 4 points of a rectangle, whose coordinates are relative to the top/left corner of the user window that the control is on.

You can explicitly lay out all of your user controls using this method, or by using the setControlAnchor command to have the user controls be dynamically sized/positioned for you. Using setControlAnchor is the preferred method, since the layout logic only needs to be specified once and the user controls will be sized/placed automatically any time the user window gets resized.

All user controls have a default size, and are created in the top left corner of the user window, so they must be placed by using either the -pos option when being created, using setControlPos, or setControlAnchor. Otherwise, all of the user controls are piled on top of one another in the top left corner of the user window.
