be used unless neither the "Emacs.EmacsFrame" resource nor the

"Emacs.EmacsFrame" resource is set; the frame

may have the wrong default size if this font doesn't exist, but some other
|

font that x-faces.el does. The workaround is to specify some font in the

resource database; I don't know a solution other than duplicating the font-
|

searching code from x-faces.el in this file.

This also means that if "Emacs.EmacsFrame" is specified as a non-

existent font, then Xt is going to substitute "XtDefaultFont" for it,

which is a different size than this one. The solution for this is to

make x-faces.el try to use XtDefaultFont. The problem with that is that

XtDefaultFont is almost certainly variable-width.
