I think we should get rid of those backends entirely. Phil stated
interesting use cases in a different thread, that might not be
accomplished with these libraries. Additionally to that I made bad
experiences with libpng and non broken but somehow not conformant png
images.

There are alternatives to using libpng and libjpeg:
* LodePNG: http://members.gamedev.net/lode/projects/LodePNG/
* STB_Image http://nothings.org/stb_image.c

I havent used the stb jpeg loader, but I switched to lodepng for the
non-gil code.
