Refactored the existing 3D node preview generation to be done synchronously, which enables their use also for creating state and item library previews for 3D nodes with ease. Fixes: QDS-5785 Change-Id: Ib493eccbc239f33bcad3301673a865494616a901 Reviewed-by: <github-actions-qt-creator@cristianadam.eu> Reviewed-by: Thomas Hartmann <thomas.hartmann@qt.io>
