[PD] [gemhead]s vs. [separator]

[João Pais]

My examples are very simple, so there won't be any problems with loops and  
no rendering orders have to be calculated.

Do I take from your comment that using [separator] does add more overhead  
than [gemhead]?

For my simple case, it seems that using both of them has the same result.  
But I would want to know what is exactly the difference.

Best,

Joao
