By isolating all font-settings into the X11 server’s resource database. It is quite a versatile system, where generic settings can conditionaly be made. xrdb(1x), the program to access the database, filters via cpp(1) preprocessor, and sets some defines to choose behaviour upon. tekonivel does this, and also sets all the colours into the XRDB too. With X11 the xrdb doesn’t need to run on the same machine as the X11 server, so all configuration can be made from the same machines where the Emacs will be running from, if need be. Tools exist to ask which fonts the X11 server has (f.ex. xlsfonts(1)), thus these preferences may be programmed.
