Clearer presentation of Vehicle Swept Paths

The Envelope Outline is good but for some reason a vehicle outline is drawn at each of the Intermediate Points, which looks messy, and if Intermediate Points are displayed then that also looks messy with lots of overlapping vehicle outlines. It would make more sense for the option to have Outlines indicated only at changes between forward and reverse manoeuvres.

Also, it would be good to be able to set a transparency value for the Fills, which then also carries through to AutoCAD.

Finally, we find that the Key would be more useful if we could have the option to show more of the design vehicle parameters, i.e. Lock to Lock time, Forwards/Reverse speed, etc.
