[MPlayer-dev-eng] PATCH - PNG transparency in vo_png.c

[it at tidetamerboatlifts.com]

Thanks,
I will try the new patch.  I was sure that my patch was not correct but I
wasn't sure exactly where to correct it.  I appreciate you taking the time
to work on it and send it back.  I'll let you know how my testing goes.
