Re: PNG pictures have gamma correction twice applied

[Richard Stallman]

      I _strongly_ stress that this
    is _not_ the proper way to fix Emacs' lack of proper color handling
    here and elsewhere.

If someone wants to implement the proper way, that would be good--but
since it is a big job, we cannot take for granted that someone will do
it in the near future.  So it is better if we install this patch.

Thanks for writing it.
