povray-3.6.2 is not available as sources for Unix, AFAICT. Am I missing
something?

trans_alpha doesn't exist for png<1.4, so if you still want to support earlier
versions, something like
#if PNG_LIBPNG_VER < 10400
#define trans_alpha trans
#endif
is needed.

Good to hear that.

Very good.

I'm sorry if the exclamation mark made you think of my request as a demand, it
was not meant in that way.

Thanks for the pointer to bugs.povray.org, I didn't find it when browsing for
where to report bugs. Do you think it would be useful to report the png problem
there (with exclamation marks this time :) )?

Thanks for your help,
 Thomas
