Fix OSX OffscreenLayerSurface (OLS) regressions (pbuffer based)

- Use pbuffer (still), don't set FBO (invisible)

- OLS (only impl is JAWTWindow now) stores the attached layer handle
  created and attached by the GLContext implementation,
  so 'others' may detach it -> NewtCanvasAWT

- NewtCanvasAWT.removeNotify() needs to ask the OLS to detach the layer
  since it's parent will be gone.

- MacOSXCGLContext destroy allows a removed OLS (see above)
