/* We have three types of Lisp objects related to font.
FONT-SPEC
Vector (length FONT_SPEC_MAX) of font properties. Some
properties can be left unspecified (i.e. nil). Emacs asks
font-drivers to find a font by FONT-SPEC. A fontset entry
specifies requisite properties whereas a face specifies just
preferable properties. This object is fully modifiable by
Lisp.
FONT-ENTITY
Vector (length FONT_ENTITY_MAX) of fully specified font
properties that a font-driver returns upon a request of
FONT-SPEC.
Note: Only the method `list' of a font-driver can create this
object, and should never be modified by Lisp. In that sense,
it may be cleaner to implement it as a Lisp object of a new
type (e.g. struct Lisp_Font).
FONT-OBJECT
Lisp object of type Lisp_Misc_Save_Value encapsulating a
pointer to "struct font". This corresponds to an opened font.
Note: The note for FONT-ENTITY also applies to this.
