	Change History (most recent first):

		<11>	 4/15/92	DCL		For New Inside Mac: Moved GetDefFontSize, GetSysFont, and
									GetAppFont from Script to Fonts.
		<10>	 7/30/91	JL		Updated Copyright.
		 <9>	 1/27/91	LN		Checked in Database generate file from DSG.
		 <8>	  1/5/91	JDR		(dba) Changed useSpline to outlinePreferred, glyphCount to
									byteCount and turnOffLineHeight to preserveGlyph.
		 <6>	12/14/90	dba		<JDR> add calls for outline fonts
		 <5>	11/28/90	JL		Put formal parameter names back.
		 <4>	 11/7/90	JL		Changed all #defines to anonymous enums
		 <3>	 11/4/90	dba		use constStr255Parameter
