-/** This class enables deployment of high-end applets which use OpenGL
- *  for 3D graphics via JOGL and (optionally) OpenAL for spatialized
- *  audio via JOAL. The applet being deployed may be either signed or
- *  unsigned; if it is unsigned, it runs inside the security sandbox,
- *  and if it is signed, the user receives a security dialog to accept
- *  the certificate for the applet as well as for JOGL and JOAL. <P>
- *
- *  The steps for deploying such applets are straightforward. First,
- *  the "archive" parameter to the applet tag must contain jogl.jar
- *  and gluegen-rt.jar, as well as any jar files associated with your
- *  applet (in this case, "your_applet.jar"). <P>
- *
- *  Second, the codebase directory on the server, which contains the
- *  applet's jar files, must also contain jogl.jar, gluegen-rt.jar,
- *  and all of the jogl-natives-*.jar and gluegen-rt-natives-*.jar
- *  files from the standard JOGL and GlueGen runtime distributions
- *  (provided in jogl-[version]-webstart.zip from the <a
- *  href="http://jogl.dev.java.net/servlets/ProjectDocumentList">JOGL
- *  release builds</a> and gluegen-rt-[version]-webstart.zip from the
- *  <a
- *  href="http://gluegen.dev.java.net/servlets/ProjectDocumentList">GlueGen
- *  runtime release builds</a>). Note that the codebase of the applet
- *  is currently the location from which the JOGL native library used
- *  by the applet is downloaded. All of the JOGL and GlueGen-related
- *  jars must be signed by the same entity, which is typically Sun
- *  Microsystems, Inc. <P>
- *
- *  To deploy an applet using both JOGL and JOAL, simply add joal.jar
- *  to the list of jars in the archive tag of the applet, and put
- *  joal.jar and the joal-natives-*.jar signed jars into the same
- *  codebase directory on the web server. These signed jars are
- *  supplied in the joal-[version]-webstart.zip archive from the <a
- *  href="http://joal.dev.java.net/servlets/ProjectDocumentList">JOAL
- *  release builds</a>. <P>
- *
- * Sample applet code:
- * <pre>
- * &lt;applet code="com.sun.opengl.util.JOGLAppletLauncher"
- *      width=600
- *      height=400
- *      codebase="/lib"
- *      archive="jogl.jar,gluegen-rt.jar,your_applet.jar"&gt;
- *   &lt;param name="subapplet.classname" VALUE="untrusted.JOGLApplet"&gt;
- *   &lt;param name="subapplet.displayname" VALUE="My JOGL Applet"&gt;
- *   &lt;param name="progressbar" value="true"&gt;
- *   &lt;param name="cache_archive" VALUE="jogl.jar,gluegen-rt.jar,your_applet.jar"&gt;
- *   &lt;param name="cache_archive_ex" VALUE="jogl.jar;preload,gluegen-rt.jar;preload,your_applet.jar;preload"&gt;
- * &lt;/applet&gt;
- * </pre>
- * <p>
- * 
- * There are some limitations with this approach. It is not possible
- * to specify e.g. -Dsun.java2d.noddraw=true or
- * -Dsun.java2d.opengl=true for better control over the Java2D
- * pipeline as it is with Java Web Start. However, the
- * JOGLAppletLauncher tries to force the use of
- * -Dsun.java2d.noddraw=true on Windows platforms for best robustness
- * by detecting if it has not been set and asking the user whether it
- * can update the Java Plug-In configuration automatically. If the
- * user agrees to this, a browser restart is required in order for the
- * change to take effect, though it is permanent for subsequent
- * browser restarts. <P>
- * 
- * The behavior of the noddraw-related dialog box can be changed via
- * two applet parameters. The <CODE>jogl.silent.noddraw.check</CODE>
- * parameter, if set to <CODE>"true"</CODE>, silences the two dialog
- * boxes associated with this check, forcing it to always be performed
- * and deployment.properties to be silently updated if necessary
- * (unless the user previously saw such a dialog box and dismissed it
- * by saying "No, Don't Ask Again"). The noddraw check can be disabled
- * completely by setting the <CODE>jogl.disable.noddraw.check</CODE>
- * applet parameter to <CODE>"true"</CODE>. <P>
- * 
- * The JOGL (and optionally JOAL) natives are cached in the user's
- * home directory (the value of the "user.home" system property in
- * Java) under the directory .jogl_ext. The Java Plug-In is
- * responsible for performing all other jar caching. If the JOGL
- * installation is updated on the server, the .jogl_ext cache will
- * automatically be updated. <p>
- * 
- * This technique requires that JOGL has not been installed in to the
- * JRE under e.g. jre/lib/ext. If problems are seen when deploying
- * this applet launcher, the first question to ask the end user is
- * whether jogl.jar and any associated DLLs, .so's, etc. are installed
- * directly in to the JRE. The applet launcher has been tested
- * primarily under Mozilla, Firefox and Internet Explorer; there may
- * be problems when running under, for example, Opera. <p>
- *
- * It has been discovered that the Talkback agent in Mozilla / Firefox
- * has bad interactions with OpenGL applets. For highest performance,
- * we recommend disabling the Talkback agent; find talkback.exe, run
- * it, and follow the directions for turning it off. Please see
- * <a href="http://www.javagaming.org/forums/index.php?topic=12200.30">this
- * thread</a> on the javagaming.org forums and
- * <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=326381">this
- * thread</a> on the Mozilla bug reporting database. <p>
