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.
