There is a patch in bugzilla that implements a new smoothing algorithm
(http://bugzilla.gnome.org/show_bug.cgi?id=104611). I try to apply the
patch some time ago, but I get a segmentation fault. I really don't go
further to see where the bug was, but I want to try make this work soon
only to see what is the result, because there are some issues related
with the implementation of this algorithm, how you can see in the
bugzilla page.

I'm reading somethings related with digital image processing and there
are a lot of interesting informations, but test these things and realize
how they can be suitable/implemented for/in a magnifier take some time.
I think that some methods can be used and I want to test then in the fly
soon.
