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
