[cairo] pdf analysis

Hi Carl,

In the meantime, I'm certainly not aware that cairo is doing anything
invalid in its PDF creation, nor "stripping" any image information.


So what about the PDF reading? How is it done by cairo? I'm currently 
using cairo with cairowrapper to create a online application that 
requires reading of PDFs.
By PDF I meant ones generated by AI(adobe illustrator).

Thanks,
Fan
