+;;;; * .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
;;; point-and-click: (mouse-1) click on a graphical object;
;;; grob-property-list: (mouse-3) click on a graphical object.
