  **  resize.js
  **      This bit of Javascript is a set of logic to help with window
  **  resizing, using the agent channel to request screen resizes.
  **
  **  It's a bit tricky, as we want to wait for resizing to settle down
  **  before sending a size.  Further, while horizontal resizing to use the whole
  **  browser width is fairly easy to arrange with css, resizing an element to use
  **  the whole vertical space (or to force a middle div to consume the bulk of the browser
  **  window size) is tricky, and the consensus seems to be that Javascript is
  **  the only right way to do it.
