php-src/ext/gd/gd.c
Christoph M. Becker 18a9ae412f Fix #77943: imageantialias($image, false); does not work 
Firstly, we must not call `gdImageSetAntiAliased()` (which sets the
color to anti-alias), but rather modify the `gdImage.AA` flag.
Furthermore, we have to actually use the supplied boolean value.

We also make sure that we don't attempt to enable anti-aliasing for
palette images.
