PURPOSE: Keeps spatial querying accurate after the shape extent has changed.

BEHAVIOR: Refreshes the shape bounds stored in the layer spatial index, typically by replacing the previous indexed extent with the current one.

USAGE: Use this method after editing geometry when index maintenance is not handled automatically by the layer.

CONSTRAINTS: Effective only when the owning layer uses a spatial index.
