OK, thanks. will try to remember that. -- but in this case  
(important/useful parameter...) I am still wondering, why the same value  
(say: scale=750) leads to totally different figure size in the pdf output  
for two different machines/OSes?

I understand that scale=1000 means "original size" but in want sense? it  
seems to dependent on the machine/engine's idea of dpi resolution or  
something like that ...
