width (swidth), e.g. `semi-compressed'.

font determined by the other attributes (those may be inherited
from the `default' face).
+ 15. A face name or list of face names from which to inherit attributes.
+
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
There is also a global face alist `Vface_new_frame_defaults'. Face
definitions from this list are used to initialize faces of newly
created frames.

A face doesn't have to specify all attributes. Those not specified
have a value of `unspecified'. Faces specifying all attributes but
the 14th are called `fully-specified'.
Face realization.
-
+
After all face attributes for a character have been determined by
merging faces of that character, that face is `realized'. The
realization process maps face attributes to what is physically
width---tries to find a best match for the specified font height,
etc.

specify alternative font families to try if a family specified by a
face doesn't exist.
+ 3. Setting face-font-registry-alternatives allows the user to

Usually, the realization process is already finished when Emacs

Initialization of basic faces.
The faces `default', `modeline' are considered `basic faces'.
basic faces are realized for CHARSET_ASCII. Frame parameters are
used to fill in unspecified attributes of the default face. */
