  18 /*  SYNOPSIS */
  19          AROS_LHA(struct Window *, window, A0),
  20          AROS_LHA(struct IntuiMessage *, imsg, A1),
  21
  22 /*  LOCATION */
  23          struct IntuitionBase *, IntuitionBase, 151, Intuition)
  24
  25 /*  FUNCTION
  26     Private: send an IntuiMessage to an Intuition window
  27
  28     INPUTS
  29     window - The window to which the IntuiMessage shall be sent
  30         imsg   - The IntuiMessage to send, which must have been allocated with
  31          AllocIntuiMessage.
  32
  33     RESULT
  34         none
  35
  36     NOTES
  37         The caller of this function should first check himself
  38     whether window->UserPort is NULL. And in this case do not
  39     call this function at all.
  40
  41     If inside this function the window->UserPort turns out to
  42     be NULL, then what happens is, that the IntuiMessage is
  43     immediately ReplyMessage()ed in here, just like if this was
  44     done by the app whose window was supposed to get the
  45     IntuiMessage.
  46
  47     The protection with Forbid() is necessary, because of the
  48     way shared window userports are handled, when one of this
  49     windows is closed, where there is also just a protection with
  50     Forbid() when stripping those IntuiMessages from the port
  51     which belong to the window which is going to be closed.
  52
  53     This function does not check whether the window to which
  54     the IntuiMessage is supposed to be sent, really wants to
  55     get the IDCMP in question, that is, whether the corresponding
  56     flag in window->IDCMPFLags is set.
