42 | /* This sucks: this is the first default that x-faces.el tries. This won't | |
43 | be used unless neither the "Emacs.EmacsFrame" resource nor the | |
44 | "Emacs.EmacsFrame" resource is set; the frame | |
45 | may have the wrong default size if this font doesn't exist, but some other | |
46 | font that x-faces.el does. The workaround is to specify some font in the | |
47 | resource database; I don't know a solution other than duplicating the font- | |
48 | searching code from x-faces.el in this file. | |
49 | ||
50 | This also means that if "Emacs.EmacsFrame" is specified as a non- | |
51 | existent font, then Xt is going to substitute "XtDefaultFont" for it, | |
52 | which is a different size than this one. The solution for this is to | |
53 | make x-faces.el try to use XtDefaultFont. The problem with that is that | |
54 | XtDefaultFont is almost certainly variable-width. | |
55 | ||
56 | #### Perhaps we could have this code explicitly set XtDefaultFont to this? | |
