bug#1728: bitmap font scaling problem

[Werner LEMBERG]

[emacs CVS 2008-12-27]

I'm now running fontconfig 2.6.0, with bitmap fonts enabled.

Selecting the `set default font' menu, `emacs -Q' now offers

  fixed Standard 9

as the default, which works fine.  However, selecting

  fixed Standard 24

(which is my preferred size), the GTK menu correctly shows the ETL
font in the right pixel size, but selecting it makes Emacs use

  xft:-ETL-Fixed-normal-normal-normal-*-40-*-*-*-c-*-iso10646-1

This looks like a selection or scaling bug.  Emacs should simply take
what the menu offers, without further font size interpretation.  It is
of course debatable whether `24' is to be handled as a pixel or point
size for a bitmap font, but this is a GTK issue, and it shouldn't be
Emacs's job to `fix' the font manager's decision.

I'm running X.Org 7.1.99.902, with 128dpi, using GTK 2.10.6.

Do you still see this problem with latest CVS?

Using the CVS version from today, it seems to work now, thanks.  The
24~pixel size is properly announced and selected as 14pt.

Just curious: would it be possible to extend the font dialogue so that
I can select the foundry also?

I don't think so; the dialogue is a standard GTK dialogue, and Emacs
does not have much control over it.
