.to_yaml() misses some layer properties defined in Klayout

[smgitrep]

I created a lyp file in Klayout and converted it to a yaml file using .to_yaml(), but the resulting yaml file does not include all layer properties. For example, it leaves out the "stiple" pattern and line "style" defined in Klayout.

yes, the LYP misses some layer properties

Originally I wrote the whole LayerView processing stuff to avoid using klayout (it was an optional dependency at the time) but now that kfactory/klayout are part of the requirements this should be refactored to use the kfactory lyp import/export.

Thank you for the comments. I decided to setup layerviews using a yaml file, and then, convert it to lyp for use in Klayout. This seems easier. I found hatch (Klayout "stiple") and line styles (Klayout "style") in one of the python scripts included with gdsfactory. See attached txt file. I also found colors can be set using color names (strings) in the yaml file and to_lyp converts them to hex values for use in Klayout.
