GraphUI: Add Shape.IO_DISCARDED and update it @ Scene/Group draw(); Prepare for experimental occlusion-culling
TreeTool's cullShapes(), actually a naive dumm occlusion test (*RENAME IT*),
would need to realize whether the shape/groups actually cover shapes below,
i.e. are not on same Z-Axis and transparent.
Hence, this is disabled in code and we rely on the Z buffer still,
just an idea ..
