PURPOSE: Register an aggregated shape that represents a group of source features in the vector layer.
BEHAVIOR: Adds _shape to the temporary aggregation output set used during rendering. If _attr is provided, it is attached to shape.TagPointer and managed by the aggregator. Registered shapes are removed after the draw cycle completes.
