Bug 64970

From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.1 (X11; Linux i686; U;) Gecko/20020417

Description of problem:
The default Xft configuration file, "/etc/X11/XftConfig", tends to
preferentially use substitute fonts even when a proper match is available.  For
example, it contains lines like this:

   match any family == "Verdana"  edit family += "Luxi Sans";

Now, Verdana is a fairly high quality font that many of us have on our systems
by way of Microsoft Windows.  The edit above uses "+=", though, which *prepends*
"Luxi Sans" to the family list.  Thus, even if Verdana is available, the lower
quality Luxi Sans will be used instead.

These "+=" lines should be changed to "=+", so that the substitute family is
appended rather than prepended.  That way, the substitute will only be used if
the original request cannot be found.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Install Verdana on a Linux box.  You can find this on a friendly neighborhood
Windows machine.

2. Select Verdana for use in some Xft-enabled application.

Actual Results:  Luxi Sans is used where Verdana was requested.

Expected Results:  Given that Verdana was installed on the system, and Verdana
was requested, Verdana should have been used.

Additional info:

The tricky part of reproducing the bug is finding a convenient Xft-enabled
application.  If you have a decent GNOME2 installation sitting around, the
"gnome-font-properties" capplet is a good one.  Click on one of the font
buttons, and select "Verdana" in the font picker dialog.  The font button shows
"Luxi Sans".
