Sticker shortcut standard

[Philippe Hurbain]

Our current rules on sticker shortcuts are:

- The shortcut may not include more than one part, although that part may be a shortcut part.

- The shortcut may not be a flat sticker on the flat surface of the part unless that surface is not parallel with one of the 3 cardinal planes (X,Y,Z). Existing sticker shortcuts that do not conform to this rule can remain in the Official Library and not be made obsolete.

- The sticker(s) must entirely fit on the part, with no portions of the sticker(s) extending beyond the boundaries of the part.

- The sticker(s) must be applied in the same location(s) as shown in the instructions for the official LEGO model from which the sticker(s) originate(s).

Note: The second and third items have been superseded and will be removed.
