bug#12996: Font rendering for emacs-24 in Mac OS X is fuzzy

[David Kanter]

When I build the emacs-24 Bazaar branch for Mac OS X, the GUI font
rendering is fuzzy.

I build Emacs.app with ./autogen.sh; ./configure --with-ns; make
bootstrap; make install. The font issue does not exist with Emacs
24.2, and it does not exist with trunk. The font issue still occurs
with Emacs -Q (built from emacs-24)

Below is output from M-x report-emacs-bug
