Binary package hint: libx11-data

http://bugs.freedesktop.org/show_bug.cgi?id=3104 describes the compose-table-cache thats available in X11. As far as I can see this is not used in Ubuntu (hardy). Because it can improve startup time (40-200ms) and memory use (240k) for every X application, maybe the postinst script of libx11-data (which contains the compose tables) could generate these caches during installation. A blog post describing the compose table cache in less technical terms is at http://kdemonkey.blogspot.com/2008/04/magic-trick.html.
