[Papervision3D] adding copyTransform to Matrix3D and getting back a pure array

[John Grden]

Ok, that sounds good. I'm going to try and put some of that functionality in
StarSystemConnection and play a bit.  If it seems like we'll need that more
often, then I might look into adding it to PV3D and get you in the loop as I
do it.

Thanks all,
