Notes	The Master X and Master Y Resolution fields can be used to specify
	600 dpi resolution for a pattern originally designed at 300 dpi.
	However, a pattern which was designed at 600 dpi is not available
	for selection at 300 dpi resolution.
	Patterns are identified by some value (ID number). This is the current
	pattern ID number.
	If the Pattern ID command is not used to assign an ID number to the
	user pattern, the existing (current) pattern ID value is used. If a
	pattern is already associated with the ID, that pattern is replaced with
	the new pattern.
