Title:
FFe+UIFe: Upload Oneiric Ubuntu
mikkel: I spent several hours looking into selective optimisation and
the internals of libjpeg last night. (There doesn't appear to be any
code available)

mikkel: yeah, from memory there was a high-frequency cornfield photo in
the last release that just wouldn't accept its destiny. This is part of

This especially unbearable on high end screens.
