** 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.
