What I like with current png.* code in the tree is a tiny footprint
comparable to libpng. Also as it was already mentioned we do not really
need majority of libpng code, particularly esoteric colorspaces,
interlaced images or 8bpp high color (how can you call 8bpp a high
color at all?). Speed is not a question here, as you do not have
to decode images in real time anyway.

Another huge advantage is removing libpng dependency. This eases life
of porters a lot and again, libpng is fat.
