pretty please can we kill the png optimizer?

[Matthias Klose]

Hi,

we don't ship cd images anymore, we are not limited to CD sizes, and as long as
we don't hit some 2GB limit, we shouldn't optimize for size.  This "optimizer"
adds for some packages 100% build time, in rare occasions up to 2000%.  This is
not worth the savings.  If we want to optimize for size, this should be done by
test rebuilds and individual patches, not consuming scare buildd resources.

thanks, Matthias
