 According to the libpng ChangeLog
 [http://www.libpng.org/pub/png/src/libpng-1.2.x-to-1.4.x-summary.txt]:
 {{{
 2. b. We removed the typecasted NULL definitions such as

          #define png_voidp_NULL    (png_voidp)NULL

       If you used these in your application, just use NULL instead.
 }}}
 I've updated fract4d/c/imageIO.cpp following 2b and it compiles fine.

 I have a MacIntel with Leopard 10.5.8
