+** Convert everything that uses post-command-idle-hook
+ to use idle timers instead.

** Fix the kill/yank treatment of invisible text. At the moment,
invisible text is placed in the kill-ring, so that the contents of
the ring may not correspond to the text as displayed to the user. It
** Make monochrome images display using the foreground and background
colors of the applicable faces.
+** Face remapping.
+
** Add support for rendering antialiased text, probably using
XRender/Freetype.
