	Change History (most recent first):

		<13>	 7/31/91	JL		Updated Copyright. Restored Comments.
		<12>	 1/29/91	JL		Changed parameter name of PixMap32Bit to from offscrrenPixMap to
									pmHandle.
		<11>	 1/28/91	LN		Checked in Database generate file from DSG. Grouping enums into
									groups of 20.
		<10>	 1/25/91	stb		JDR: add const on non-VAR parameters
		 <9>	 1/15/91	KON		Change useMFTempBit to UseTempMemBit. [csd]
		 <8>	11/28/90	JL		Put formal parameter names back.
		 <7>	 11/4/90	dba		shortened inline for OffscreenVersion; use (void) instead of ();
									got rid of some extraneous parameter names
		 <6>	  10/990	JAL		Changed __Safe_Link to _CPlusPlus.
		 <5>	  9/1/90	dvb		Beautify.
		 <4>	 3/29/90	KON		Put parameter size (in bytes) in high word of d0, trap selector
									in low word.
		 <3>	 3/27/90	KON		Added useMFTemp flag, keepLocal flag, and prototypes for
									selectors 19-23.
