Ah, ok. I can put the idea of stubs in the docs too - this is an entirely 
comprehensible concept for those who understand basic engraving principles, as 
this is how engravers reserve space in many cases. They use physical objects 
that take up space but are never printed to block other objects.

Hmm...will think it over.  I agree with you that it's confusing - I think that 
a combination of documentation and perhaps warnings would help users with this.
