-- Based on minetest.rotate_and_place
--[[
Attempt to predict the desired orientation of the pillar-like node
defined by `itemstack`, and place it accordingly in one of 3 possible
orientations (X, Y or Z).
Stacks are handled normally if the `infinitestacks`
field is false or omitted (else, the itemstack is not changed).
* `invert_wall`: if `true`, place wall-orientation on the ground and ground-
orientation on wall
This function is a simplified version of minetest.rotate_and_place.
The Minetest function is seen as inappropriate because this includes mirror
images of possible orientations, causing problems with pillar shadings.
