Although your PDF knowledge is probably vastly superior to my own, it does not mesh with what I understand about PDF. According to
(what I remember from) the PDF specs, PostScript instructions are used for page layout and vector art. And PDF files can contain embedded fonts used to render TEXT when it is being displayed. Unless the displayed content consists of pre-rendered text made up of vector artwork, it makes no sense to embed fonts. What are the fonts USED for if the text has already been converted to pre-rendered lines and curves?
Is it true for "all" PDFs? You are confusing me. Now I have to go find and read a PDF spec again...
