Port the WinForms GraphicsHelper program walker to a toolkit-neutral figure list (move/line/arc) with its layer routing: cuts without tabs, leads, etches, and a material fill without break cuts whose tab-gapped pieces are bridged. Suppressed moves are skipped and marks never bound the fill. PartDisplayGeometry picks the fill as LayoutPart does (common-line members, break cuts, open cuts) and keeps display-only entities; PartLabels ports the label points. ViewTransform carries DrawControl's world/screen mapping and zoom rules. PlateOverlays computes what the view draws around parts (sheet, edge spacing, irregular usable area, clamps, cut-off strokes, rapids, pierce points, cut direction, offset outline, support) through the existing Core code. PlateViewOptions reads and writes the View toggles under the WinForms PlateViewDrawRapid/PlateViewDrawBounds names. WinForms still draws with GraphicsHelper; nothing there changes.
