Merged JSR-231 branch on to the main JOGL trunk. The main trunk now

contains the evolving JSR-231 Reference Implementation and the JSR-231
branch is permanently closed.

+/** Defines the threading model for the implementation of the classes
+    in this package.
+
+    <P>
+
+    OpenGL is specified as a thread-safe API, but in practice there
+    are multithreading-related issues on most, if not all, of the
+    platforms which support it. For example, some OpenGL
+    implementations do not behave well when one context is made
+    current first on one thread, released, and then made current on a
+    second thread, although this is legal according to the OpenGL
+    specification. On other platforms there are other problems.
+
+    <P>
+
+    Due to these limitations, and due to the inherent multithreading
+    in the Java platform (in particular, in the Abstract Window
+    Toolkit), it is necessary to limit the multithreading occurring in
+    the typical application using the JOGL API. This has been done by
+    forcing all OpenGL-related work for GLAutoDrawables on to a single
+    thread. In other words, if an application uses only the
+    GLAutoDrawable and GLEventListener callback mechanism, it is
+    guaranteed to have the most correct single-threaded behavior on
+    all platforms.
+
+    <P>
+
+    Applications using the GLContext makeCurrent/release API directly
+    will inherently break this single-threaded model, as these methods
+    require that the OpenGL context be made current on the current
+    thread immediately. For applications wishing to integrate better
+    with the single-threaded model, this class provides public access
+    to the mechanism used by the JOGL implementation. Users can
+    execute Runnables on the internal thread used for performing
+    OpenGL work, and query whether the current thread is already this
+    thread. Using these mechanisms the user can move work from the
+    current thread on to the internal OpenGL thread if desired.
+
+    <P>
+
+    This class also provides mechanisms for querying whether this
+    internal serialization of OpenGL work is in effect, and a
+    programmatic way of disabling it. Currently it is enabled by
+    default, although it could be disabled in the future if OpenGL
+    drivers become more robust on all platforms.
+
+    <P>
+
+    In addition to specifying programmatically whether the single
+    thread for OpenGL work is enabled, users may switch it on and off
+    using the system property <code>jogl.1thread</code>. Valid values
+    for this system property are:
+
+    <PRE>
+    -Djogl.1thread=false     Disable single-threading of OpenGL work
+    -Djogl.1thread=true      Enable single-threading of OpenGL work (default)
