Tk::Splashscreen - display a Splashscreen during program initialization.

       Component subwidgets can be accessed via the Subwidget  method.   This  mega  widget  has  no  advertised
       subwidgets. Instead, treat the widget reference as a Toplevel and populate it as desired.

<ButtonPress-3>
       Notifies the Splashscreen to set a mark for an impending move.

   <ButtonRelease-3>
       Moves the Splashscreen from the mark to the cursor's current position.

       For programs that require large load times, it's a common practice to display a Splashscreen that
       occupies the user's attention.  This Toplevel mega widget provides all the display, destroy and timing
       events.  All you do it create the Splashscreen mega widget, populate it as you see fit, then invoke
       Splash() to display it and Destroy() to tear it down.

       Important note: be sure to sprinkle update() calls throughout your initialization code so that any
       Splashscreen events are handled.  Remember, the screen may be animated, or the user may be simply moving
       the Splashscreen about.

        $splash = $mw->Splashscreen;

        ... populate the Splashscreen toplevel as desired ...

        $splash->Splash(4000);

        ... program initialization ...

        $splash->Destroy;

$splash->Splash([milliseconds]);
       If milliseconds is specified, it's the minimum number of milliseconds the Splashscreen should  remain  on
       the screen.  This value takes precedence over that specified on the Splashscreen constructor call.

   $splash->Destroy([milliseconds]);
       If  milliseconds  is specified, it's the minimum number of milliseconds the Splashscreen should remain on
       the screen.  This value takes precedence over that specified on the Splash() call, which takes precedence
       over that specified during Splashscreen construction.

       Tk::Splashscreen - display a Splashscreen during program initialization.

       The following option/value pairs are supported:

       -milliseconds
           The minimum number of milliseconds the Splashscreen should remain on the screen.  Default is 0, which
           means  that the Splashscreen is destroyed as soon as Destroy() is called.  Otherwise, Destroy() waits
           for the specified time interval to elapse before destroying the Splashscreen.

        $splash = $parent->Splashscreen(-opt => val, ... );
