--[[ This mod registers 3 nodes:
|
|
- One node for the horizontal-facing dispensers (mcl_dispensers:dispenser)
|
|
- One node for the upwards-facing dispensers (mcl_dispenser:dispenser_up)
|
|
- One node for the downwards-facing dispensers (mcl_dispenser:dispenser_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.
