Years ago I investigate this kind of problem for my application. I can't
optimize PNGReader on image side. I tried to connect some C library but no
success.
My time was limited for this issue. And it was not really critical for me.
So I gave up.

After that Athens was announced. And as I understand Cairo can work with
png-files directly without loading it to image side. I not try it. Maybe
you can experiment with this.
