I think McCLIM acts alright to not send repaint events as no window
damage is reported. 

To fix this, Hello World should also listen to the
window-configuration-event.

(defmethod handle-event ((pane hello-world-pane) (event window-configuration-event))
  (handle-repaint paint +everwhere+))

..I hope +everywhere+ is the correct constant for the everywhere
region..

So maybe add a mental rule (and/or as footnote to the Hello World
example): whenever the content of a window is dependend on the window
size and we are using handle-repaint, remember to trigger this repaint
also on a window-configuration-event.
