Copycat object

TODO: Fill this in!

(This is basically revisiting the idea here in light of some ideas hashed out in the other page mentioned next.)

There are some opportunities here that present themselves, for instance re-introducing objects into the rendering stream as suggested here.

In reviewing a bit, probably graphics or display object methods would provide a means to do this, where supported (it's genuinely difficult for some cases, e.g. groups, lines, meshes), or else the objects in question could expose such a method, if it was felt that the result could measure up to the challenge!

Once instantiated, the relevant properties could probably be enumerated, on first use, by what the object in question provides, otherwise providing nil. (TODO: Off-hand, three different means of instantiation.) Before submission, would query a dirty flag and synchronize propertties.

This is medium- to high-priority, if it does ultimately seem the way to go.
