I should qualify that by saying "...under copyright law."  Contract law
permits to be just as cussed in your licence conditions as you wish,
e.g., "you agree that these chess pictures may be used in combination
with works created by anyone who is not a left-handed Scandinavian", 
in which case use of my separate works, seeing as I'm a sinistral
Viking-descendant, would violate contract requirements without regard to
whether derivative work law (a concept from copyright law) applies.

Anyhow, GPLv2 and v3 are, explicitly, grants of rights under _copyright_
law.
