pdftoppm is an unfortunate name - it produces most formats and we
always asked it to give us .png output.

I need to check out ImageMagick and see how well it supports PDFs with
embedded form objects, asian fonts, different font models and so on.
For our own test suite it really needs to support all the common stuff
in PDF.
