# ==========================================

# Setting new private attributes on PyVista objects is allowed by default.

# Do not allow setting new attributes.

# Note that this state is global and will persist between function calls. Set it
# back to its original state explicitly.

# Use it as a context manager instead. This way, the state is only temporarily
# modified and is automatically restored.
