  27 /*  FUNCTION
  28     Determines the current mouse position relative to the upper-left
  29     corner of a custom gadget.
  30     It is recommended not to call this function!
  31
  32     INPUTS
  33     gadget - The gadget to take as origin
  34     ginfo - The GadgetInfo structure as passed to the custom gadget hook routine
  35     mousepoint - Pointer to an array of two WORDs or a structure of type Point
  36
  37     RESULT
  38     None. Fills in the two WORDs pointed to by mousepoint.
  39
  40     NOTES
  41     This function is useless, because programs which need this information
