stableBackbuffer	back to summary
private RTTexture stableBackbuffer An offscreen surface that acts as a persistent backbuffer, currently only used when dirty region optimizations are enabled in the scenegraph. In OpenGL, the contents of a window's (hardware) backbuffer are undefined after a swapBuffers() operation. The dirty region optimizations used in the Prism scenegraph require the window's backbuffer to be persistent, so when those optimizations are enabled, we insert this special stableBackbuffer into the swap chain. In createGraphics() we return a Graphics object that points to this stableBackbuffer so that the scenegraph gets rendered into it, and then at present() time we first copy stableBackbuffer into the window's hardware backbuffer prior to calling swapBuffers().

lockResources	back to summary
public boolean lockResources(PresentableState pState) Implements com.sun.prism.Presentable.lockResources. Doc from com.sun.prism.Presentable.lockResources. Locks any underlying resources needed for a createGraphics/prepare/present sequence and returns a boolean indicating if the presentable needs to be recreated. If the method returns true and the Presentable implements `GraphicsResource` then its `dispose()` method will be called prior to recreating a new `Presentable` object and so no resource should need to be locked in that case. The resources will be unlocked in either `prepare()` or `present()`. Annotations @Override
