	Change History (most recent first):

	   <SM5>	  8/5/93	JDR		integrate component mgr from reality
	   <SM4>	 7/21/93	RC		House Cleaning from Reality
		 <6>	 7/16/93	JDR		Added SupportNativeComponents and kComponentIsNative.
		 <5>	 6/13/93	JDR		Rolled in the ComponentMgr sources from QuickTime 1.6.
		 <4>	11/12/92	JDR		Created kComponentInitialTableEntries which was set to 32
									entries in System 7.1, but I cut it back to only 16 to help save
									some RAM for the general user.
		 <3>	12/12/91	DTY		Get rid of the spaces in the file names
		 <2>	 12/5/91	YK		Rolled in QuickTime GM:
										grow cmpnt table by smaller steps to preserve system heap
		 <8>	 9/25/91	BAL		Added an internal flag to mark cloned app-heap compononents as
									subordinate to their sys heap parents.
		 <7>	 5/18/91	dvb		Thing->Component
		 <6>	  5/2/91	BAL		overlap rtDesc.FlagsMask and rtRefcon again.
		 <5>	  4/1/91	MK		make rtRefcon and rtFlagsMask separate again
		 <4>	 3/28/91	BAL		Do some file management.  Added parentThing and Captured flag.
		 <3>	 2/21/91	MK		slime some globals for codec manager
		 <2>	 2/16/91	BAL		Added InitThingManager call.
		 <3>	 12/30/90	bal		changed name to thing manager
		 <2>	 10/06/90	dvb		Make it work

	To Do:
