32 ;; This file is totally bogus in the context of Emacs. Much of what it does
|
|
|
33 ;; is really in the provice of faces (for example all the style parameters),
|
|
|
34 ;; and that's the way it is in GNU Emacs.
|
|
|
35 ;;
|
|
|
36 ;; What is needed for fonts at the Lisp level is a consistent way to access
|
|
|
37 ;; face properties that are actually associated with fonts for some rendering
|
|
|
38 ;; engine, in other words, the kinds of facilities provided by fontconfig
|
|
|
39 ;; patterns. We just need to provide an interface to looking up, storing,
|
|
|
40 ;; and manipulating font specifications with certain properties. There will
|
|
|
41 ;; be some engine-specific stuff, like the bogosity of X11's character set
|
|
|
42 ;; registries.
