If I do "ldd /usr/lib/cups/filter/pdftoraster-poppler" on Natty, I see 
that the filter is not linked with libcairo. So does the filter really 
use Cairo? Splash seems to be built in in Poppler, as there is no such 
thing as a libsplash and Splash-related .h files are in libpoppler-dev.

Does subpixel rendering really matter for printing?
