--[[ This mod registers 3 nodes:
2017-02-14 02:33:58 +01:00
- One node for the horizontal-facing dropper (mcl_droppers:dropper)
- One node for the upwards-facing droppers (mcl_droppers:dropper_up)
- One node for the downwards-facing droppers (mcl_droppers:dropper_down)
3 node definitions are needed because of the way the textures are defined.
All node definitions share a lot of code, so this is the reason why there
are so many weird tables below.
