  This is the main script for the Virtualcube JavaScript applet.

  The applet inserts itself into all div elements of the HTML page
  with class "virtualcube".

  Here is a minimal HTML code that is required to include the applet
  into a HTML page:

  <!DOCTYPE html>
  <html>
  <head>
  <meta charset="utf-8">
  <script type="module" src="lib/virtualcube.mjs"/>
  </head>
  <body>
  <div class="virtualcube" kind="..." stickersImage="..."></div>
  </body>
  </html>

  The div element can have the following attributes:
    kind            Specifies the cube model to be displayed.
                    Supported values:
                      "Rubikscube"
                      "Pocketcube"

    stickersimage   Specifies the URL of the stickers image.
                    See supplied example image.


  The applet replaces the content of the div element with the following structure.

  <div class="virtualcube" cube="..." stickersimage="...">
    <canvas class="cube-canvas"></canvas>
    <div class="controls">
      <div class="toolbar">
        <button class="reset-button"><span>Reset</span></button>
        <button class="play-button"><span>Undo</span></button>
        <button class="step-backward-button"><span>Previous</span></button>
        <button class="step-forward-button"><span>Next</span></button>
        <button class="undo-button"><span>Undo</span></button>
        <button class="redo-button"><span>Redo</span></button>
        <button class="scramble-button"><span>Scramble</span></button>
      </div>
      <div class="script">...<span class="currentMove">...</span> <span class="nextMove">...</span>...</div>
    </div>
  </div>

  If the applet fails to run, it leaves the div elements untouched.
  You can put a placeholder into the div element.

  Legacy Java Applet support:
  --------------------------------
  To ease the transition from Java Applets to JavaScript, this
  applet also replaces applet tags with code="PocketPlayer.class",
  "PocketPlayerFlat.class", "RubikPlayer.class", or "RubikPlayerFlat.class".
