+;;;; * .cff MUST NOT be in fc's fontpath.
+;;;; - workaround: remove mf/out from ~/.fonts.conf,
+;;;; instead add ~/.fonts and symlink all /mf/out/*otf there.
+;;;; - bug in fontconfig/freetype/pango?
+
+;;; * check: blot+scaling
+;;; * Figure out and fix font scaling and character placement
+;;; * EC font package: add missing X font directories and AFMs
+;;; * User-interface, keybindings
+;;; * Implement missing stencil functions
+;;; * Implement missing commands
+;;; * More information in stencils, e.g., location and grob tag.
+;;; * Embedded Lily:
+;;; - allow GnomeCanvas or `toplevel' GtkWindow to be created
+;;; outside of LilyPond
+;;; - lilylib.
+;;; * Release schedule and packaging of dependencies.
+;;; - g-wrap-1.9.3 is already in incoming.
+;;; - guile-gnome-platform-2.8.0 will probably be packaged early 2005.
