-  // be able to share textures and display lists with the Java2D
-  // contexts, we need to use the CGL APIs rather than the NSOpenGL
-  // APIs on the JOGL side. For example, if we create a pbuffer using
-  // the NSOpenGL APIs and want to share textures and display lists
-  // between it and the Java2D back buffer, there is no way to do so,
-  // because the Java2D context is actually a CGLContextObj and the

-  // NSOpenGLContext as its second argument. Of course there is no way
-  // to wrap an NSOpenGLContext around an arbitrary CGLContextObj.
-  //
-  // The situation we care most about is allowing a GLPbuffer to share
-  // textures, etc. with a GLJPanel when the Java2D/JOGL bridge is

-  // notion of a "mode" of both the MacOSXGLDrawable and the
-  // MacOSXGLContext. Initially the mode is "unspecified", meaning it
-  // leans toward the default (NSOpenGL). If sharing is requested
-  // between either a GLJPanel and a GLPbuffer or a GLCanvas and a
-  // GLPbuffer, the GLPbuffer will be switched into the appropriate
-  // mode: CGL mode for a GLJPanel and NSOpenGL mode for a GLCanvas.
-  // To avoid thrashing we support exactly one such switch during the
-  // lifetime of a given GLPbuffer. This is not a fully general
