That's obviously for me. The more interesting questions for me is (I was 
suprised by pdftocairo, too):
1. If I want to produce a png output,
a) which program produces the "correcter" output?
b) which program is faster?
Okay, nobody can probably answer this for all PDF. But are there any 
experiences?
2. What is with futur bugs in png output? File them to splash or file 
them to cairo?
3. Are there any plans to support CMYK output with cairo (or does it 
already support is)?
4. pdftocairo has a PDF output option. What does this mean, when 
producing a PDF with pdftocairo from a PDF? Something like a 
"normalization"?
