	File:		MenuMgrPriv.h

	Contains:	Private interface to the Menu Manager.

	Change History (most recent first):

		 <4>	 3/31/93	IH		Add CalcMenuBar call for Display Manager.
		 <6>	 11/5/92	JSM		Add interfaces to more private routines, add SavedBitsRecord and
									OffscreenBufferRecord, although we can't really represent the
									latter in C the way it's defined in assembly.
		 <5>	 9/16/92	JSM		SaveBits takes a Rect*, not a Rect.
		 <4>	  2/5/91	stb		gs: move in SaveBits, RestoreBits, DiscardBits
		 <3>	 1/21/91	DFH		(KSM) Added System Menu constants from MenuMgrPriv.a.
		 <2>	  6/8/90	KSM		Add IsSystemMenu call.
		 <1>	 5/21/90	KSM		New today.
