Sorry, I really shouldn't use gmail web interface.

I used the official gentoo ebuild in portage and it has a qt use flag
to enable it.
The ebuild doesn't seem to use any patches.
But it really doesn't matter since the rendering is worse and
introduce an unnecessary cairo dependency.

> It's wrong, look at how splashoutputdev does it (yes i know it sucks)

Sorry, I only quickly valgrinded the app and added the matching delete
for the new.
so if I understand it right, I have to use unref() instead even if I
directly allocated

As you can see in the screenshot, Splash output is antialised. but
there are minor differences in the pathes.
