Re: [Gawkextlib-developer] [gawkextlib:bugs] #8 gawk-gd translucency fix (fwd)

[<jue...@go...>]

Hello Andrew,
Evgeny's change adds just one line containing a function call.
After this change all PNG files will be saved with an alpha
translucency channel. I think this is a good idea.

Thanks to Evgeny for caring about this advanced feature and
to Andrew for caring about the GIT stuff that causes me to acquire
a spontaneous a skin rash whenevever I think about GIT.
