  property SmartSize : Integer read;

PURPOSE: Estimate shape visibility (rendered pixel area at current zoom). Enables zoom-aware LOD selection and rendering optimization (skip tiny shapes).

BEHAVIOR: Computed from extent and viewer zoom level. Accounts for projection distortion and screen size. Returns approximate pixel count.

USAGE: Visibility culling:if shape.SmartSize > 2 then Render; LOD selection:detail := SmartSize / 100;

CONSTRAINTS: Read-only. Requires valid Viewer (returns 0 if Nil). Approximate value (zoom/projection dependent).
