Bug 1202: Fix vsync regression on OSX when using CALayer On OSX using CALayer for onscreen rendering, the drawable is utilizing an offscreen FBO. Hence we need to move the vsync-skip-operation criteria, i.e. skip if offscreen, down to the implementation.
Bug 1212 - OSX: Crash using CALayer at UnsetJAWTRootSurfaceLayer0(..) w/ Java 1.8.0_60 - OSX 10.10.5 - Java 1.8.0_60 Crash using CALayer at UnsetJAWTRootSurfaceLayer0(..) as called within MacOSXJAWTWindow.invalidateNative() (caller: destroy()) on the MainThread. It has been observed that the JAWT_SurfaceLayers protocol instance 'surfaceLayers' has been pulled beforehand. 'surfaceLayers' is fetched from the locked JAWT instance via JAWT_DrawingSurfaceInfo's platformInfo. It now seems required to retain the instance at GetJAWTSurfaceLayersHandle0 and release it at UnsetJAWTRootSurfaceLayer0 to keep it alive. +++ Manually executed 'ant junit.run' on OSX, no failures or errors.
