test pdf tile

I saw in the poppler mailing list that a number of recent changes were supposed
to make poppler run faster, so I tested the a 20 Aug 2013 clone and found
pdftops that it was about 10% slower than last year.  The times are relatively
repeatable because I am reading from an SSD and writing to a RAM disk.
This isn't a bug, but some of the recent changes might have had unintended
consequences.
I tested an unpatched 0.24.0 clone against a lightly patched 0.21.0 that I have
been using for about a year.
