NAME
	GT_PostFilterIMsg -- return the unfiltered message after
	                     GT_FilterIMsg() was called, and clean up. (V36)

   SYNOPSIS
	imsg = GT_PostFilterIMsg(modimsg)
	D0                       A1

	struct IntuiMessage *GT_PostFilterIMsg(struct IntuiMessage *);

   FUNCTION
	NOTE WELL:  Extremely few programs will actually need this function.
	You almost certainly should be using GT_GetIMsg() and GT_ReplyIMsg()
	only, and not GT_FilterIMsg() and GT_PostFilterIMsg().

	Performs any clean-up necessitated by a previous call to
	GT_FilterIMsg().  The original IntuiMessage is now yours to handle.
	Do not interpret the fields of the original IntuiMessage, but
	rather use only the one you got from GT_FilterIMsg().  You
	may only do message related things at this point, such as queueing
	it up or replying it.  Since you got the message with
	exec.library/GetMsg(), your responsibilities do include replying
	it with exec.library/ReplyMsg(). This function may be safely
	called with a NULL parameter.

   INPUTS
	modimsg - a modified IntuiMessage obtained with GT_FilterIMsg(),
	          or NULL in which case this function does nothing and
	          returns NULL

   RESULT
	imsg - a pointer to the original IntuiMessage, if GT_FilterIMsg()
	       returned non-NULL.

   NOTES
	Be sure to use exec.library/ReplyMsg() on the original IntuiMessage
	you obtained with GetMsg(), (which is the what you passed to
	GT_FilterIMsg()), and not on the parameter of this function.

	Starting with V39, this function actually expects and returns
	pointers to ExtIntuiMessage structures, but the prototype was not
	changed for source code compatibility with older software.
