  33 /*  FUNCTION
  34     Add some gadgets to a window.
  35
  36     INPUTS
  37     window - Add gadgets to this window
  38     gadget - This is the list of gadgets to add
  39     position - Where to insert the gadgets in the list of gadgets
  40         already in the window. Use 0 to insert the gadgets
  41         before all others in the window or ~0 to append them.
  42     numGad - How many gadgets of the list should be added.
  43         Use -1 to add all gadgets in the list.
  44     requester - Pointer to the requester structure if the window is
  45         a requester.
  46
  47     RESULT
  48     The actual position where the gadgets were inserted.
  49
  50     NOTES
  51     The gadgets will just be added. To make them visible, you must
  52     refresh the window or the gadgets.
