I've done some very cursory testing -- I was able to view pngs with playbin2.
But that's the extent of my testing.

It was very cursory testing -- mainly to see if it would work. libpng, upon
install, puts png.h and pngconf.h in your <header install root> and these then
point to <header install root>/libpng14/ (so I didn't have to change anything
there). I then created a symbolic link from libpng14.dll.a to libpng12.dll.a
and compiled. I didn't change configure.ac. I'm not an autotools guru. So it
essentially thought png 1.4 was png 1.2.

I'd be happy to patch configure.ac if I knew how and what to do.
