I also tried to find something, and it seems Apple doesn't have docs for 
Quartz online.

|  Postscript data. IMHO you can only reference fonts which are in either
| Type 1 or OpenType format?

You can embed TrueType fonts into PostScript/PDF as Type42 font...
AFAIK Adobe's PostSCript driver for Windows does this (but not Qt 3.1/KDE 
3.1).
On th eother hand, I haven't succeeded creating PDF with OpenType font, as I 
have Windows 98 (parallel to KDE) and Win98 doesn't support OpenType at all 
(hey, we are really ahead of Microsoft here!  You can't print from KWord 
using OpenType font, but it renders fine on screen)
I also tried to export to PDf from Adobe inDesign 1.5, and it seems InDesign 
also doesn't accpet OTF fonts.

About Type1 and Type3:
--------------------------
You can embed both Type1 and Type3 fonts into PDF.
Of course, after taking it all together and thinking for a moment, it's clear 
that font handling in Windows/Mac is a nightmare, and interoperability of 
documents doens't exist.
But, it's possible to do all this.  Question is wether we want to have such a 
mess in KDE/KOffice...
