Yes, but not necessarily linearly.

The major problem with getting depth to be equal to the desired fog
level is this: I have the cs I want to translate from, as well as the
polar coordinates for the translated cs, and I have the *absolute* depth
I want to place the translated cs at -- well, actually, the depth
relative to the cs *given to the view*. I don't have my parent cs's
depth (relative to the cs given to the view). So it's hard to get the
child cs to the right depth.

One possiblity would be a coordinate system type that takes the
translation, rotation & c from one coordinate system, but the depth
relative to another coordinate system?

Another problem is that depth is also needed to orchestrate connections,
boxes, and box content: connections need to go under boxes, and box
content needs to go above.

Can you go into more detail?
