Bug 937 - JAWTWindow: Unsatisfying Visibility Computation
Simplify JAWTComponentListener's HierarchyListener: - Don't interfere w/ Component's visibility anymore! This shall reduce sideeffects. Utilize 'isShowing' in each Component specialization, i.e. GLCanvas. - On SHOWING_CHANGED if a parent caused a change of the tracked components showing state, propagate it to the offscreen-layer! - Remove all other complicated states! GLCanvas, GLJPanel: - Instead of 'isVisible()' use 'showing state', since only the 'showing state' reflects 'true' visibility throughout the hierarchy. - Add HierarchyListener and track volatile showing state to be used instead of 'isVisible'. Using a cached showing state is more efficient than quering 'isShowing()' all the time! NewtCanvasAWT: - Use 'isShowing()' instead of 'isVisible(), see above
