Hi,

I made a PNGReadWriter2 and a PNGReadWriter2Plugin with libpng support 
for fast png reading, which is needed in Sophie and future versions of 
Plopp.

Currently it can only read a png file and returns only 32bit forms.

The repository for this is http://www.squeaksource.com/PNGReadWriter2

and I build it with vmaker 3.8b6, squeak 3.9 and the squeak 3.9-8 unix 
sources.

to build it under linux, create a Makefile.inc with

  LDFLAGS           += -lpng

in platforms/unix/plugins/PNGReadWriter2Plugin


contributions, e.g. writing images, are very welcome.
