Comment(by hamish):

 oops, the fns in the last msg were already taken care of in grass source.

 as for moving png_info from png.h to pnginfo.h, see changelog starting
 http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng/libpng;a=blob;f=CHANGES;h=fb069121a45024e4904e7f4ea0636f183b7ec350;hb=refs/tags/v1.5.2#l2663

 I guess we need to set up some #ifdefs based on
 `PNG_LIBPNG_VER_MAJOR == 1` and `PNG_LIBPNG_VER_MINOR >= 5`

 but I'm not sure how the libpng15 version should look yet.
