I give up on this one. It seems to explicitly disable  
png_set_tRNS_to_alpha IF we use the local built-in PNG lib. But the  
built-in PNG lib does support png_set_tRNS_to_alpha... Mind you, we  
don't actually seem to use the png_png_set_tRNS_to_alpha flag in the  
configure script either.

Maybe it is just a leftover from the days when the built-in PNG lib  
was quite an old one?
