bug#3834: 23.0.96; font rendering issue on Mac OS X

[Adrian Robert]

I checked in a fix to the branch.  If it resolves the issue I'll copy  
it to the trunk as well.

Thanks for taking a look and making a fix.  I'd be happy to test it,  
but I haven't been building it myself.  I've been grabbing the  
pretests from here:
http://porkrind.org/emacs/

If you can provide a build or point me at some instructions on how to  
build it myself, I'll verify the fix.

Thanks,
Greg

I think the porkrind nightly builds are the trunk, so  I checked out  
the source like this:
cvs -z3 -d:pserver:anonymous@cvs.savannah.gnu.org:/sources/emacs co -r  
EMACS_23_1_RC emacs

The configure and build went smoothly:
GNU Emacs 23.0.96.1 (i386-apple-darwin9.7.0, NS apple-appkit-949.46)  
of 2009-07-16 on osiris.local

The fonts are rendered correctly.  The change you made seems to have  
done the trick.  Thanks again.

bug#3834: 23.0.96; font rendering issue on Mac OS X

[Greg Jednaszewski]

I use the 'Terminus' font in emacs, and it seems that starting with
23.0.95 (and 23.0.96 as well), emacs always wants to render the font in
bold.  It looked perfect in 23.0.94, so something has changed since
then.

Here is a screenshot of the correct font rendering in 23.0.94.  The
buffer name on the modeline is properly bold, everything else is medium:
http://attenuated.org/emacs/emacs-23.0.94.png

Here is a screenshot of the incorrect font rendering in 23.0.96:
http://attenuated.org/emacs/emacs-23.0.96.png

Here is a copy of the font for reference:
http://antihe.ro/misc/TerminusMedium.dfont

As can be seen from the screenshot, I am setting the font with:
(set-face-attribute 'default nil :family "terminus" :height 140)

Let me know if more information is needed.

Thanks,
Greg

I can't reproduce it on GNU/Linux.  I tried to use terminus
font both as X core font and as Xft font.  In both cases,
Emacs uses correct styles of terminus fonts.

I suspect it's a Mac specific problem.
