Units - rtbCamerasPlace

[wandell]

In a number of places, and rtbCamerasPlace is one example, there are factors that scale by 1000 to deal with meters and millimeters. There are rarely comments about this near the code. We need to catch these locations and deal with units more explicitly.

This might all be relatively new with code from HB and me. If we don't deal with the units throughout, say distance is sometimes meters and sometimes millimeters, we will have long term problems.
