DXF does not support shape repetition (only block repetition). Please call
library.wrap_repeated_shapes() before writing to file.
Shape repetitions are expanded into individual DXF entities.
Other functions you may want to call:
- `masque.file.oasis.check_valid_names(library.keys())` to check for invalid names
