   Day Parting Sliders
   Simon Champion. Copyright Skycom Ltd.

   This program allows users to set up their phone numbers so that their calls
   are redirected to different numbers at different times of day. They use a
   graphical slider control to build up their settings, which has full drag &
   drop capabilities.

   The program makes use of Javascript, CSS and XMLHTTPRequest, so it requires an
   up-to-date browser. It has been tested, and works, on: MSIE 6 (Windows XP),
   Firefox 2.0.0.6 (Win XP & Linux), Opera 9 (Linux), Konqueror 3.5.6 (Linux).
   However, there are a couple of browser-specific differences that the program
   has to take into account, particularly with MSIE.
   (1) Two different methods were written for displaying the background pattern in
       the slider bars. We'll call them modes "0" and "1". Mode 1 works in all
       browsers that support opacity (ie all tested except Opera); Mode 0 works
       in all browsers, and looks better than mode 1, but resizing of segments
       is *very* slow in MSIE in this mode. Therefore we prefer to use mode 0,
       but revert to mode 1 under MSIE.
   (2) Highlighting text is disabled to prevent the drag+drop functions from
       selecting chunks of the page when you drag, as this makes it very distracting
       to use. To disable highlighting in MSIE, a javascript event handler is
       required, whereas Firefox uses CSS. Opera and Konqueror do not support
       disabling of highlighting. Users of these browsers will just have to live
       with it.
   (3) XMLHTTPRequest works differently under MSIE compared to other browsers.
       See api-lite.php.js.
   Of these, only (3) is a serious issue: the first two are simply attempts to
   make it look as good as possible under every browser; the third directly affects
   crucial functionality. Fortunately though, the issue is well documented, as
   all AJAX web sites have to deal with it.

   For testing purposes, or curiosity, setting a url parameter of "slidermode=1"
   or "slidermode=0" changes the method the program uses to display the sliders,
   and allows you to see the two modes described in (2) above.
   The difference can be seen when the sliders are moved. In the absence of this
   parameter (ie normal usage), the program will use the mode that best suits the
   particular browser (ie mode 0 looks better, but is too slow under MSIE).
   "slidermode=2" (solid colours) is also available, but is deprecated.

   Also note, that in order to work on all browsers, the main page requires the
   doctype to be specified. It has been tested with the html/loose.dtd doctype,
   and should work with strict.dtd as well, but does not work on all browsers
   without it (especially MSIE).
