	Change History (most recent first):

		 <7>	 7/23/91	JL		Checked in File from database. Changed #defines to enums.
									Adjusted comments. Moved PictInfoID typedef to the beginning of
									the Type declarations to match Pascal file.
		 <6>	 1/16/91	JDR		(dba) Renamed METHOD_SYSTEM to systemMethod, METHOD_POPULAR to
									popularMethod, and METHOD_MEDIAN to medianMethod
		 <5>	 10/9/90	JAL		CPlusPlus compatibility.
		 <4>	 9/21/90	gbm		(Actually DDG) Updating selectors to work with ProcHelper.
		 <3>	 9/19/90	DDG		Name changes for some of the parameters for a few of the
									routines.
		 <2>	 9/18/90	DDG		Fixed the header.
		 <1>	 9/18/90	DDG		first checked in

	To Do:
