;	Change History (most recent first):
;
;		<12>	 7/28/92	DCL		Moved applicationFloatKind & systemFloatKind constants out of
;									the public eye and into the private Layers header file. At the
;									request of TechPubs, and with moral support from Dean, Greg and
;									Kenny.
;		<11>	 2/22/92	DTY		Why is there no underscore in front of the NewLayers macro?
;		<10>	 8/22/91	JSM		Clean up header.
;		 <9>	 1/30/91	gbm		sab, #38: Change the Ôalready including this fileÕ variable to
;									all uppercase (for security reasons)
;		 <8>	  1/3/91	VL		(RLC) Added a new private call RedrawAll.
;		 <7>	  9/7/90	dba		get rid of warning for the good of all mankind
;		 <6>	  9/7/90	DFH		Changed SetLayerLock to GetDeskPort
;		 <5>	 7/23/90	EMT		Changed IsLayerLocked to WindowType.
;		 <4>	 5/30/90	DC		Merge with layers.a - add interface for GlobalPortRect
;		 <3>	 5/30/90	EMT		Converted to use DoDispatch and added macros for newer routines.
;		 <1>	  4/2/90	EMT		first checked in.
