but must set it in the core metric of the target application

since...

    jsdialog: consume .uno:LineWidth double value

added parameters for online, but with parameters its no longer considered a
simple slot and for non-simple slots the auto-conversion of values to/from
twips isn't done.

there's probably a much and older deeper bug here, but lets get this
known broken line width working
