Re: Using -Tpdf rather than -Tps and then ps2pdf

Tadziu, Deri, thanks for looking into this where looking is the key word.

Tadziu, your eyes had an answer that my eyes could see but not identify.

On the page I provided, I replaced the 'pi' towards the top of the right
column with an 'a' and the beta in the middle of that column with 'b'/

I re-rendered both the same way and The two outputs now match visually, at 
least to my eyes.  Certainly the bottom of the 2nd column is identical
between the two rather than being one line short in the earlier PDF.

So, that does suggest that Tadziu's original thoughts on the handling of 
that Symbol font is on the right track.

Thanks - Damian
