Yes, this was discovered by one of the gimp developers literally
minutes after I made the 0.4.0 release.  It's generally considered
good style for gobjects to provide a C accessor function for each
property, and vica-versa, for exactly this reason.

Generally, the ability to turn off antialiasing is not necessary or
desirable, but there are certainly image-manipulation situations where
having crisp, full-intensity borders is more important than subpixel
accuracy.  This is why pretty much every operation in GIMP can have
the antialiasing turned off.  It would be a shame if the poppler
plugin couldn't do this, when the old ghostscript-based plugin could.

We'll see what we can come up with.

We'll stay in touch.
