testserver.DEFAULT_CLIENT_DATA

Stand-ins for what a browser would report, sent when the session starts.

Keys are named after the readers on ClientData. An output_* key applies to every output, so output_width becomes each output's .clientdata_output_<id>_width; every other key is session-wide. Without these a size-aware renderer such as render.plot raises a silent exception and produces nothing, and session.clientdata.url_pathname() never resolves.
