^ Attempt to predict the desired orientation of the facedir-capable node

defined by itemstack, and place it accordingly (on-wall, on the floor, or

hanging from the ceiling). Stacks are handled normally if the infinitestacks

field is false or omitted (else, the itemstack is not changed). orient_flags
|
||||
is an optional table containing extra tweaks to the placement code:
|
||||
invert_wall: if true, place wall-orientation on the ground and ground-
|
||||
orientation on the wall.
|
||||
force_wall: if true, always place the node in wall orientation.
|
||||
force_ceiling: if true, always place on the ceiling.
|
||||
force_floor: if true, always place the node on the floor.
|
||||
|
||||
The above four options are mutually-exclusive; the last in the list takes
|
||||
precedence over the first.
|
||||
|
||||
force_facedir: if true, forcably reset the facedir to north when placing on
|
||||
the floor or ceiling
