Description: Fix building against libpng 1.5.
 From the libpng homepage...
 
 The libpng 1.5.x series continues the evolution of the libpng API,
 finally hiding the contents of the venerable and hoary png_struct and
 png_info data structures inside private (i.e., non-installed) header
 files. Instead of direct struct-access, applications should be using
 the various png_get_xxx() and png_set_xxx() accessor functions, which
 have existed for almost as long as libpng itself. (Apps that compiled
 against libpng 1.4 without warnings about deprecated features should
 happily compile against 1.5, too.
