	Change History (most recent first):

		<25>	 3/30/92	DTY		#1025416,<DDG>: Define Gestalt selector for Skia. We’re putting
									it here because there’s no GestaltPrivate.h, and Process Manager
									is the only thing in the System that’s using this selector right
									now.
		<24>	 3/25/92	DTY		#1024114,<pvh>: Add inline for PEntryFromProcessSerialNumber
		<23>	 1/14/92	YK		Removed obsolete constant for the TSM.
		<22>	 1/11/92	YK		Two more calls for TSM. NewTSMLayerOwner to get the event for
									the floating window. RouteEventToSWM to do the bottom line
									input.
		<21>	 1/10/92	YK		Added definitions for supporting the Text Services Manager.
		<20>	 2/21/91	DFH		dba,#82504, #82681, #83168, #83182, #83207: Added
									SysZoneFloatSizes.
		<19>	 1/28/91	DFH		JSM,#81425:Add EnableSwitching and DisableSwitching calls.
		<18>	 1/21/91	DFH		(KSM) Removed Process Menu IDs, since they are now in
									MenuMgrPriv.h, as the Application Menu IDs.
		<17>	12/20/90	DFH		(dba) Added GetNextHighLevelEvent.
		<16>	12/14/90	DFH		Added SynchIdleTime.
		<15>	 11/4/90	dba		use (void) instead of (), also add some const to parameters
		<14>	 9/10/90	DFH		Changed iconHelpString to itemHelpString (wow!).
		<13>	 7/25/90	DFH		Added InitApplication, CleanupApplication, and SndAppDead.
		<12>	 7/19/90	DFH		Removed iconColor from AddAppleMenuItem.
		<11>	  6/8/90	DFH		Added ProcessMenuResourceID and ProcessMenuID.
		<10>	 5/20/90	ngk		Used VNProcPtr in volume Notification procs.
		 <9>	  5/7/90	DFH		Get/SetProcessTrapAddress use TrapType.
		 <8>	 4/16/90	DFH		Reorganized the file to group the call glue with the
									structures.  Now uses unsigned fields whenever possible.
									Fixed AddAppleMenuItem to use unsigned short for itemStyle
									(since Pascal and C don't agree on how to pass a byte).
		 <7>	 4/11/90	KSM		Added auxMenuHelpString to AuxMenuItemRec.
		 <6>	 3/20/90	DFH		Added iconColor and itemHelpString, and changed itemStyle to short
		 <5>	  2/8/90	DFH		Fixed this list (had comment ender on BEGIN EASE line).
		 <4>	  2/8/90	DFH		Copied projector revision comments to this file.
		 <3>	  2/5/90	DFH		Added enteredDebugger.
		 <2>	  1/3/90	DFH		Added itemStyle to AddAppleMenuItem.  Reversed order of GetProcessFromLayer parms.
	To Do:
