The second reason is that GTK XEmacs does not use these
resource files for setting the default text font. You can
change the foreground and background colours, or change the
background pixmap, but if you use the file above only the
menubar and other widgets will have their font changed.
Fixing this will require changes to some low-level code
within XEmacs. Solution suggestions are welcome.
Why can't you just write code analogous to the way that X resources are
currently handled?
