- Bug #170546 Save/Export Selection as SVG

(Note: I don't imply that this is a duplicate report - only that exporting (saving a copy as) SVG file without hidden layers might pose similar issues to address as exporting a selection based on all visible objects (in all layers): there might be referenced objects on the hidden layers (objects which are referenced by visible objects via <use>) which would have to be included nevertheless, otherwise the exported drawing will render differently).
