Of the problems I've reported, your branch fixes these two:

font-lock faces use different font with font-backend
http://lists.gnu.org/archive/html/emacs-devel/2008-03/msg00651.html

font height problems with font-backend
http://lists.gnu.org/archive/html/emacs-devel/2008-03/msg00620.html

This issue is still present:

Xresource pane.menubar.*font no longer takes effect
http://lists.gnu.org/archive/html/emacs-devel/2008-02/msg00314.html
http://lists.gnu.org/archive/html/emacs-devel/2008-02/msg01683.html

Also, I have a new issue now, in that Emacs starts with the right
font, but in the wrong size. I have in ~/.Xdefaults:

Emacs.font: -misc-fixed-medium-r-normal-*-14-*-100-100-*-*-iso8859-1

But Emacs starts with a bigger font (misc fixed 9x15 it seems).
If I select 7x13 or 7x14 from the shift-mouse-1 "Misc" menu, I get the
font I want.

Thank you for confirming them.

Ok, I'm now investigating it.

I've just installed a fix.

Whoops, I just noticed that faces with a bold attribute are still
using a slightly different font.

Works for me. Thanks!

Please show the results of C-u C-x = on the character of
default face and on the questionable characters.

Default face:

        character: l (108, #o154, #x6c)
preferred charset: ascii (ASCII (ISO646 IRV))
       code point: 0x6C
           syntax: w    which means: word
         category: a:ASCII graphic characters 32-126 (ISO646
         IRV:1983[4/0])
               l:Latin r:Japanese roman
      buffer code: #x6C
        file code: not encodable by coding system iso-latin-1-unix
          display: by this font (glyph code)
     -misc-fixed-medium-r-normal--14-130-75-75-c-70-iso8859-1 (#x6C)

Bold face:

        character: p (112, #o160, #x70)
preferred charset: ascii (ASCII (ISO646 IRV))
       code point: 0x70
           syntax: w    which means: word
         category: a:ASCII graphic characters 32-126 (ISO646

Ah, I see.  You wrote that you have this font setting.

Emacs.font: -misc-fixed-medium-r-normal-*-14-*-100-100-*-*-iso8859-1

When I run the command
  % xlsfonts -fn -misc-fixed-*-*-*-*-14-*-100-100-*-iso8859-1
I got this result:
  -misc-fixed-medium-r-normal--14-110-100-100-c-70-iso8859-1

So, Emacs preferred to use it for bold by making it
artificially bold (by overstriking).

But, actually that font is an alias of
  -misc-fixed-medium-r-normal--14-130-75-75-c-70-iso8859-1.
and that font has this bold version:
  -misc-fixed-bold-r-normal--14-130-75-75-c-70-iso8859-1

Very complicated...

I've just installed a better but a little bit slower font

Thank you - everything seems to work now. I have no more complaints! :)

That's good.  Thank you for the help for fixing bugs.

Re: font-backend branch

Any chance of arranging commit mails for this branch?

Or do you expect it to be short-lived and quickly merged?

Yes.  As soon as Windows port code gets stable, I'll merge
it to the trunk.

I don't know what has happened to break the Windows code. The ChangeLog 
does not appear to offer any clues.
 From what I can figure out, I think the default face is not being 
initialised properly. default_face->lface[LFACE_FAMILY_INDEX] is "*", 
likewise for other font related values, so any faces that inherit from 
the default face eventually end up calling font_open_entity with 
#<font-entity nil nil nil nil nil nil nil ...>.

Also (font-xlfd-name (font-at 1)) in *scratch* returns 
"-*-*-*-*-*-*-*-*-*-*-*-*-*-*", while (font-at 1) returns #<font-object 
"Courier New">

In trunk, these return "-outline-courier 
new-normal-normal-normal-mono-13-*-*-*-m-*-iso10646-1" and #<save_value 
ptr=0x01c66d00 int=4>
 respectively.
