56 | be used unless neither the "Emacs.EmacsFrame" resource nor the | |
57 | "Emacs.EmacsFrame" resource is set; the frame | |
58 | may have the wrong default size if this font doesn't exist, but some other | |
59 | font that x-faces.el does. The workaround is to specify some font in the | |
60 | resource database; I don't know a solution other than duplicating the font- | |
61 | searching code from x-faces.el in this file. | |
62 | ||
63 | This also means that if "Emacs.EmacsFrame" is specified as a non- | |
64 | existent font, then Xt is going to substitute "XtDefaultFont" for it, | |
65 | which is a different size than this one. The solution for this is to | |
66 | make x-faces.el try to use XtDefaultFont. The problem with that is that | |
67 | XtDefaultFont is almost certainly variable-width. | |
