Ok, I managed to change my png  plugin to handle cleaning out all
transparent pixels.

What do you say? Is it interesting to go in right now? If it is a PNG 
recomendation, then it might be a nice add on, and it is small enough 
to go in even now, before the first pre-2.0.

a 640x480 pix image with a transparent hole of about half it's size 
got a 15% file size decrease.

I will polish my changes a little and submit the patch do bugzilla. If 
anyone wanna try it, just tell me now.
