Without this, various sky rendering modes exhibit artefacts in low-

negligible. (And Rembrandt already had to work this way)

Reset: alternate property copying strategy.
Search the tree for leaves / sub-trees with a particular attribute set.
This permits both sparse selection as well as selection by sub-tree.
(This is needed for PRESERVE attribute, and once new reset is switched

attributes completely)

Reset: use ref-counting to own subsystems.
Change the subsystem-group and manager code to use shared-ptr references

track-to animation: 2dof rotation for slave object.
Slave objects can now rotate around two axis to always track the
target - even when it is outside the plane perpendicular to the
lock-axis of the root object. This allows for example animating
levers with non-parallel axis of rotation connected with a rod.
