Qt4 binding of poppler (using Splash backend) has
a method to configure the anti-aliasing and hinting;
Thus, it would be possible for the application
using poppler-qt4 to have a preference switch.

But poppler cairo backend does not have a method
for such purpose. I've ever written a patch to add
such method. See discussion beginning from
Anyway, there was no consensus whether such feature
is good idea, because too many configurable parameters
do not help the user but confuse them.

# BTW, I've not worked for the anti-aliasing on
# graphic object. I only tested the font/text objects.
