- click-and-drag doesn't work for X11 mouse report overriding

- add X11 mouse highlighting mode?

- colour text cursor (xterm `-cr' option)

- speed-up screen refreshes

- a better resizing mechanism that avoids truncating lines and also
  unwraps autowrapped lines?  Why bother, xterm doesn't.

- add support for spawning modules (like the way fvwm does).
  It should then be possible to make a standalone Tek or other graphics
  window and even some simple pop-up mouse menus that could communicate
  with rxvt, but not bloat its size.  Nice idea, but I'll never have time
  to even start, so eager volunteers would be nice.
