Using EPset_Drawing data instead of camera props on drawing print #3396

Previously if you change `HasUnderlay` in pset it caused errors because camera properties `has_underlay` wasn't updated.
Still some work need to be done for updating keep camera properties in sync with pset - probably we can should call something like `tool.Drawing.import_drawing()` on EPset_Drawing edit
