Just return def as default if any errors

public static int getIntParameter( Applet applet, String ParamName, int def)

parseColour

Parse a colour string, in format described above.
		return defaultColour if needed

public static Color parseColour( String strColour, Color defaultColour)

getBgColour

Get a background colour from parameter or default,
ie from parameter "bgcolor" or "bgcolour"

The second form below returns the largest y reached.

public static void ShowInfo( Component c, Graphics g, String lbl, Color BgColour, Color FgColour)
public static int ShowInfo( Rectangle bounds, Graphics g, String lbl, Color BgColour, Color FgColour)

PHDStringTokenizer is similar to StringTokenizer. It has fewer methods and does not implement Enumeration.
More importantly only one delimiter is skipped at a time, eg if ";" is the delimiter then "a;;c" has 3 tokens.
