+ 14. Font pattern, or nil. This is a special attribute.
When this attribute is specified, the face uses a font opened by
that pattern as is. In addition, all the other font-related
attributes (1st thru 5th) are generated from the opened font name.
and is used to ensure that a font specified on the command line,
for example, can be matched exactly.
+ 17. A fontset name.
+
Faces are frame-local by nature because Emacs allows to define the
same named face (face names are symbols) differently for different
frames. Each frame has an alist of face definitions for all named
is realized, it inherits (thus shares) a fontset of an ASCII face
that has the same attributes other than font-related ones.
- Thus, all realized face have a realized fontset.
