Fix Bug 691 (part-3): NSOpenGLLayer::openGLContextForPixelFormat(..) on main-thread deadlock'ed due to locked shared context
NSOpenGLLayer::openGLContextForPixelFormat(..) is performed on main-thread at 1st NSOpenGLLayer display method.
This happened irregulary, i.e. sometimes (T0) right after NSOpenGLLayer creation and attachSurfaceLayer()/AddCASublayer(..),
sometimes later (T1).
NSOpenGLLayer::openGLContextForPixelFormat(..) uses the passed shared user context.
The shared user context is locked at NSOpenGLLayer's creation (T0) and if performed at this early time
the call deadlocks due to pthread_mutex wait for the shared user context.
This fix performs NSOpenGLLayer creation and layer attachment while the shared user context
is kept unlocked and enforces NSOpenGLLayer display and hence NSOpenGLLayer::openGLContextForPixelFormat(..).
Added CGL.setNSOpenGLLayerEnabled(..) to enable/disable NSOpenGLLayer - currently not used.
- Passed AddRemove tests for GLCanvas/Swing and GLWindow/NewtCanvasAWT w/ 100 loops on Java6 and Java7 on OSX.
- Passed Instruments Leaks test w/ 10 loops on Java6 and Java7
