What are Z and W coordinates?

What are Z and W position coords of Image?
According to docs, I can set position of image by method:

setPosition( [x] [, y] [, z] [, w])

What are then these last two coords?
Thanks!

As far as I’m aware, they’re not used for anything.

I would say these coords are for 3D space

I used the z co-ordinated to set the depth, same as setDepth()
