CircleNode
Builds the leaf around circle's geometry.
Parameters
circle
The geometry to decorate; its components are copied.
style
The concrete paint; the circle default when omitted.
tags
Free-form tokens riding the leaf; empty by default.
Builds the leaf as a copy of node: the same geometry, and node's own style and tags unless either is overridden.
Construction copies node's components, so the copy carries the same geometry at full Double precision. Overriding style or tags swaps that part alone — the other still comes from node.
