3D layout

[trusktr]

I'd like to extend this to 3D.

I see there's lines starting with Z to indicate z-index, but I suppose that isn't really depth.

I'd like to lay things out depth-wise too.

f.e. put items at opposite corners of the 3D layout:

H:|-[child1(child3)]-[child3]-|
V:|-[child1(child3)]-[child3]-|
D:|-[child1(child3)]-[child3]-|

where D is for depth. Or maybe we can extend Z for that, and set the Z size to work in that space.

But if we use Z, maybe X and Y could work in place of H and V, for consistency (and D as alias for Z).
