DDD 3.3.1 adds multiple local font server entries in font path

[John Klingler]

Every time you run an application in ddd 3.3.1, it add the localhost 
font server, tcp/127.0.0.1:7100 to the
X server's fontpath without checking to see if it is already there (see 
below). This seriously degrades system
performance. It does the same when displaying on a remote host, which I 
am sure was not the programmer's
intention.

Font Path (eng8):
/home/john/.kde/share/fonts/override,/usr/lib/X11/fonts/misc/,/usr/lib/X11/fonts/Speedo/,/usr/lib/X11/fonts/Type1/,/usr/lib/X11/fonts/75dpi/,/usr/lib/X11/fonts/100dpi/,/home/john/.kde/share/fonts,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100,tcp/127.0.0.1:7100 


The code to do this correctly is fairly trivial, but I'll send it to you 
if you like.

By the way, I don't know about other vendor's Linux distributions but 
starting with Red Hat 8.0, the font
server (XFree86 fs) is, by default, configured not to listen on tcp 
sockets (for "security" reasons), so you
might want to verify tcp connectivity. For a local font server, 
UNIX/:7100 gets better performance. (You
know, I guess, that you can't count of the port being 7100, either.)
