commit ceb8b18f5b7437ba7438c428c3c78e4d8d67fee3
Author: LuboÅ¡ LuÅák <l.lu...@suse.cz>
Date: Fri Jun 22 17:19:12 2012 +0200
use generic names rather than specific algorithm names when scaling
The Lanczos scaling is of very good quality, but it's rather slow,
which can be very noticeable with large images, so it's not a very
good default for everything. And in general, it's not good to refer
to a specific algorithm when all one usually wants is fast/default/best.
Some of these changes are a bit of a guess between default/best,
but the general logic is that best should be used only for images
that won't be large or where the possible waiting does not matter.
