GLContext*/GLDrawableHelper: Fix consistency of recursive makeCurrent()/release()/destroy() calls ; Enable context switch tracing ; GLCanvas: proper AbstractGraphicsDevice destruction
GLContext*/GLDrawableHelper: Fix consistency of recursive makeCurrent()/release()/destroy() calls Utilizing volatile and lock.tryLock(0) for lockConsiderFailFast(), reducing redundant synchronization and using RecursiveLock implicit sync. GLContext 'early-out' is the case where the thread already holds the context, ie. context is already current and the native makeCurrent is skipped. makeCurrent()'s 'early-out' w/o incr. the recursive lock of GLContext and it's NativeSurface could lead to asymetry in lock/unlock count with release()/destroy() calls. The 1st release actually released the native ctx already. Properly utilize recursive lock/unlock in all cases and impl. 'early-out' after locking. Following the above in GLDrawableHelper.invokeGL()'s 'early-out' case as well, ie calling makeCurrent()/release() symmetrical. Introduce GLDrawableHelper.disposeGL(), which issues dispose on all GLEventListeners within a current context and issued context destruction directly. This simplifies GLAutodrawable's destroy/dispose calls and ensures that the above sequence of events happens atomically (lock is being hold until destruction). Enable context switch tracing If property 'jogl.debug.GLContext.TraceSwitch' is defined, trace context switch. GLCanvas: proper AbstractGraphicsDevice destruction
