	Contains:	Routines which patch the Window Manager traps.

	Change History (most recent first):

		 <7>	11/15/92	JDR		Changed QuickDraw.h to not use the dangerous pattern, which
									defines a pattern as a struct. This code was calling BlockMove
									to copy the 8 byte pattern, but patterns are structs so Pattern
									= Pattern works fine. I fixed the includes a bit too, and the
									dependencies were wrong by the way so I fixed them as well.
		 <6>	 5/19/92	YK		#1030028: Remove <4> and <5> since SWM is not an application
									now.    Roll back to <3>.
		 <5>	 1/14/92	YK		Added checking code for TSM. Removed the include statement that
									was added at <4>.
		 <4>	 1/10/92	YK		Added support for the special-hacked-background app for the Text
									Services Manager in c_initwindows.
									Include MFPrivate.h to do that.
		 <3>	 1/21/91	DFH		(KSM) Process Menu is now called Application Menu.
		 <0>	  9/2/86	ELR		New Today.
