+If optional arguments FACE and FRAME are specified, return only fonts

+
+PATTERN should be a string containing a font name in the XLFD,
+Fontconfig, or GTK format. A font name given in the XLFD format may
+contain wildcard characters:
+ the * character matches any substring, and
+ the ? character matches any single character.
+ PATTERN is case-insensitive.
+
+The return value is a list of strings, suitable as arguments to
+\`set-face-font'.
+
+Fonts Emacs can't use may or may not be excluded
+even if they match PATTERN and FACE.
+The optional fourth argument MAXIMUM sets a limit on how many
+fonts to match. The first MAXIMUM fonts are reported.
+The optional fifth argument WIDTH, if specified, is a number of columns
+occupied by a character of a font. In that case, return only fonts
+the WIDTH times as wide as FACE on FRAME."
