The following variables exist but are not documented in the emacs info:

mac-allow-anti-aliasing  mac-command-modifier
mac-control-modifier     mac-function-modifier
mac-option-modifier

They are originally from the carbon port and they used to be documented.
The info section that describes them seems to have been removed,
probably when the nextstep port took over. They are still relevant
should be documented.

I was poking around and noticed that the mac-* have been renamed to ns-* 
names. They are still not documented, however. Sorry to cause any confusion 
by refering to their old names.

Other font backends that support anti-aliasing use an :antialias 
property on the font to disable or use a different type of antialiasing 
for that font. There are a lot of extra font properties like this that 
aren't documented either, especially in the xft and w32 font backends.

Confusingly, this is not a variable that controls anti-aliasing, but
it changes a font rendering engine so it uses lighter anti-aliasing.
This facility seems to be deprecated as of Mac OS X 10.5, so I'd
suggest removing this variable together with the corresponding NS
variable, ns-use-qd-smoothing.

Still this applies to another NS variable, ns-antialias-text.

Sorry, this description itself seems to be confusing.  I meant, "if
the variable is set to non-nil, it selects another font rendering
engine whose rendering results in lighter anti-aliasing."
