Actually .. after reviewing and fixing regressions .. it looks more simple:

Strategy for JAWTWindow:
  if OSX >= 10.6.4 && container-is-Applet
    if setJAWTVersion(CALayer)==OK
      OSXJAWTWindow is set to offscreenLayerSurface-mode

If GLDrawable's NativeWindow is a direct offscreenLayerSurface-mode (GLCanvas)
or it's parent NativeWindowHolder (ie NewtCanvasAWT),
it's created as an Offscreen/Pbuffer .. and our NSOpenGLLayer is being used
and attached.

+++

The other changes are more related to the above situation,
ie. a NativeWindow may become offscreen on-the-fly (NEWT).

Resize w/ offscreen -> recreate.

General 'harden' the existing code, ie removing bugs
not visible due to the previous value-space,
which has been widen now thx to this new use-case.

The good thing is that our architecture didn't need to change.
One just need to make sure that the GL code (GLEventListener)
is correct in respect to recreation (multiple init/destroy cycles).

Sure it is, at least on paper/spec.

Actually all browsers are supposed to use the new CALayer now
so we shall work well with GLCanvas and NewtCanvasAWT.

The latter will work better, since it can support 'recreation'
and hence reparenting (CALayer/NSView) and resize.

You are welcome .. sure we need to be platform complete.
Even though I am not a OS X 'fan',
this experience lead to another code review and bug fixes.

I will send an email soon when this branch works 'well',
ie tested w/ Applets etc..
