Bug 1489 - GraphUI Group: Resolve Performance Regression in Scene.pickShape(): Drop invisible and clipped shapes

After implementing Bug 1487 (Frustum Clipping/Culling) and using thousands of shapes within one Group mostly culled (outside of frustum),
overall mouse Scene.pickShape() caused tremendous lagging.

This is caused by Scene.pickShape() traversing through _all_ shapes,
rendered ones, invisible ones and culled ones.

+++

Solution is to have Scene and Group provide a pre-sorted list
of actually rendered shapes, i.e. isVisible() and not culled.

Scene.pickShape() can now use this reduced and pre-sorted list
reducing the load considerably.

+++

Further
- cleanup TreeTool

- rename Container methods:
-- setFrustumCullingEnabled() -> setPMvCullingEnabled()
-- isFrustumCullingEnabled() -> isPMvCullingEnabled()

- supply Container with
-- isCullingEnabled()
-- List<Shape> getRenderedShapes()
-- isOutside()
-- isOutside2()
-- forAllRendered()
