Indicates that subsequent commands up to a DrawPopPattern() command
comprise the definition of a named pattern. The pattern space is assigned
top left corner coordinates, a width and height, and becomes its own
drawing space. Anything which can be drawn may be used in a pattern
definition. Named patterns may be used as stroke or brush definitions.
