/**
* NEWT Utility class MainThread
*
* <p>This class provides a startup singleton <i>main thread</i>, from which a new thread with the
* users main class is launched.<br>
* Such behavior is necessary for native windowing toolkits, where the windowing management must
* happen on the so called <i>main thread</i> e.g. for Mac OS X !<br>
* Utilizing this class as a launchpad, now you are able to use a NEWT multithreaded application
* with window handling within the different threads, even on these restricted platforms.<br>
* To support your NEWT Window platform, you have to pass your <i>main thread</i> actions to {@link
* #invoke invoke(..)}, have a look at the {@link com.jogamp.newt.macosx.MacWindow MacWindow}
* implementation.<br>
* <i>TODO</i>: Some hardcoded dependencies exist in this implementation, where you have to patch
* this code or factor it out.
*
* <p>If your platform is not Mac OS X, but you want to test your code without modifying this class,
* you have to set the system property <code>newt.MainThread.force</code> to <code>true</code>.
*
* <p>The code is compatible with all other platform, which support multithreaded windowing
* handling. Since those platforms won't trigger the <i>main thread</i> serialization, the main
* method will be simply executed, in case you haven't set <code>newt.MainThread.force</code> to
* <code>true</code>.
*
* <p>Test case on Mac OS X (or any other platform):
*
* <PRE>
* java -XstartOnFirstThread com.jogamp.newt.util.MainThread demos.es1.RedSquare -GL2 -GL2 -GL2 -GL2
* </PRE>
*
* Which starts 4 threads, each with a window and OpenGL rendering.<br>
