I think scons should be able to build Csound on a clean system with just
libsndfile added. I don't have a problem looking for libpng and building it
etc., but I want to be able to build a 'base' system without any extra dependencies
(except for libsndfile). That was the case until the image opcodes were
added. All we need is for scons to look for png.h and configure the build
accordingly.

By the way, zlib is also now a dependency, because libpng depends on it.

libpng seems likely to build on everything, so what's the
