/*
A tool to stress-test poppler rendering and measure rendering times for
very simplistic performance measuring.
TODO:
* make it work with cairo output as well
* print more info about document like e.g. enumarate images,
streams, compression, encryption, password-protection. Each should have
a command-line arguments to turn it on/off
* never over-write file given as -out argument (optionally, provide -force
option to force writing the -out file). It's way too easy too lose results
of a previous run.
