Description Sven Gothel 2013-02-14 03:59:27 CET 
Our created CALayer and NSOpenGLLayer, attached to the JAWT surface
are not released when we properly try to release them via our release calls to:
  - CGL.releaseNSOpenGLLayer(..) 
  - OSXUtil.RemoveCASublayer(..)
  - OSXUtil_DestroyCALayer(..)

The native NSOpenGLLayer's GL-Context is also retained.

This leaks leads to stalling and eventual crash of the desktop.
Comment 1 Sven Gothel 2013-02-14 04:18:03 CET 
Updated complete release sequence ..

Context unrealized:
  - JAWTWindow.detachSurfaceLayer() -> OSXUtil.RemoveCASublayer(..)
  - CGL.releaseNSOpenGLLayer(..) 
 
JAWTWindow.destroy()
  - MacOSXJAWTWindow.UnsetJAWTRootSurfaceLayer(..)
  - OSXUtil.DestroyCALayer(..)
