The composed shape is covered by copyright if you don't arrive at 
it independently... Which is unlikely for dlang.org. No different 
than a melody.

But all you need is to get written permission to modify it and 
use it for promoting commercial products related to D as covered 
by dlang.org without compensation. No reason to make it complex.
