export_icons.py
Laedt alle Material-Symbols-Outlined Icons herunter die unsere WERKZEUGE-
Sidebar benutzt, und konvertiert sie zu PNG (32x32) fuer Rhino-Toolbars.

Ausgabe-Ordner: ./icons_export/
  dossier_icons/
    svg/   — Originale SVGs (skalierbar)
    png/   — 32x32 PNGs fuer Rhino .rui Buttons

Konvertierung SVG->PNG nutzt 'rsvg-convert' wenn installiert, sonst Mac's
'qlmanage' (immer verfuegbar) als Fallback.

Verwendung:
