Many distro's won't allow font anti-aliasing for legal reasons (i
presume this is what your talking about), I'm not sure where and on
which level its done in this case but you should probably presume it
doesn't exist if you want your apps to be consistent. I don't know much
about app images but it sounds like the systems fontconfig setting are
still being used.
