Just because I'm "naive" and taking exams in school, it doesn't mean 
I'm young. I was born 8 years after the first transistor was invented 
(the year Einstein died).

With my background in graphics I had some encounter with such things 
(e.g., Adobe Font Metrics). So I guessed it might be due to some such 

Thanks a bunch for spelling it out.

This would seem to mean that LaTex could still be modified to make 
font handling much easier than it presently is.

You really have a wonderful storehouse of poignant quotations!
