The idea is to prepare a default list of hidden layers in a drawing template (for example surfaces and curves).
Our drawing layers are independent from the model.
Be able to copy the status of the 3D model to take over the management of drawing layers, even if the drawing and 3D layers have the same name.
Actually, we define the template with ignore_model_layer_status and draw_layer_overrides_model.
We have to uncheck draw_layer_overrides_model to copy the layer status from the 3D.
