Fixed an endianness bug in the PNG I/O functions which occurred when 16bit
...
grayscale PNGs were used. libpng doesn't automatically convert from host
endianness to big endian as the PNG standard demands. You have to explicitly
tell it to do this or it will write out the 16bit pixel data in host order
which result in the wrong thing happening on little endian chips. Similarly
for reading PNGs.
