	SPECIAL NOTE FOR HEADLESS SYSTEMS
	---------------------------------
	If you get a "cannot connect to X11 server" when running certain
	parts of this component under Bluedragon (Linux), you must
	add "-Djava.awt.headless=true" to the java startup line in
	<bluedragon>/bin/StartBluedragon.sh.  This isssue is discussed
	in the Bluedragon Installation Guide section 3.8.1 for
	Bluedragon 6.2.1.

	Bluedragon may also report a ClassNotFound exception when trying
	to instantiate the java.awt.image.BufferedImage class.  This is
	most likely the same issue.

	If you get "This graphics environment can be used only in the
	software emulation mode" when calling certain parts of this
	component under Coldfusion MX, you should refer to Technote
	ID #18747:  http://www.macromedia.com/go/tn_18747
