  34
  35 /*  FUNCTION
  36         Changes the values in the PropInfo-structure of a proportional
  37         gadget and refreshes the specified number of gadgets beginning
  38         at the proportional gadget. If numGad is 0 (zero), then no
  39         refreshing is done.
  40
  41     INPUTS
  42         gadget - Must be a PROPGADGET.
  43         window - The window which contains the gadget
  44         requester - If the gadget has GTYP_REQGADGET set, this must be
  45             non-NULL.
  46         flags - New flags
  47         horizPot - New value for the HorizPot field of the PropInfo
  48         vertPot - New value for the VertPot field of the PropInfo
  49         horizBody - New value for the HorizBody field of the PropInfo
  50         vertBody - New value for the VertBody field of the PropInfo
  51         numGad - How many gadgets to refresh. 0 means none (not even
  52             the current gadget) and -1 means all of them.
  53
  54     RESULT
  55         None.
  56
  57     NOTES
  58         If NewModifyProp does not work for you, check if you
  59         really have a gadget with GTYP_PROPGADGET set. If you
  60         create a new gadget object from PROPGCLASS, you
  61         might very well get a GTYP_CUSTOMGADGET gadget.
  62         As a workaround, you might have to set the
  63         gadget type to GTYP_PROPGADGET manually during the
  64         call to NewModifyProp. Intuition does this, too.
