I have incorporated this as it passes the existing regression tests and
improves output.

I saw nothing here for the type0 font issue ... but I think you've given a
good hint in your writeup.

> currently the pdf to image conversion does only work partially. there are a few problems
i would like to address with the patch:
> - draw ALL jpeg image which are inlined in the pdf doc.
>   some of the jpeg image have some kind of ".Adobe"
>   header instead of the "JFIF" header. ImageIO is unable  
>   to read the jpegs starting with the ".adobe" header.
> - catch a few nullpointer exceptions so that the draw
>   "flow" is not interrupted
> - currently the PDType0Font class draws nothing at all,
>   resp. throws which breaks as well the draw "flow".
>   because i did not know how the type0 font should be
>   drawn i simply extended from type1 (which is not cool)
>   so that at least text is drawn.
> a lot more pdfs are drawn as images with this changes in a more or less good quality.
> you will find all "touched" files in the attached zip file.
> btw: i did the relying on the "PDFBox-0.7.4-dev-20070716" dev load.
