--[[
todo -- make scaffolds do side scaffold blocks, so that they jut out.
todo -- Also, make those blocks collapse (break) when a nearby connected scaffold breaks.
todo -- add in alternative bamboo styles to simulate random placement. (see commented out node box definitions.
todo -- Add Flourish to the endcap node for bamboo.
todo -- mash all of that together so that it drops as one item, and chooses what version to be, in on_place.
todo -- Add in Extras.
todo -- fix scaffolding placing, instead of using on_rightclick first.

todo -- make graphic for top node of bamboo.
todo -- add bamboo to junk items in fishing.

waiting on specific things:
todo -- Raft -- need model
todo -- Raft with Chest. same.
todo -- handle bonemeal...

Notes:
When bone meal is used on it, it grows by 1–2 blocks. Bamboo can grow up to 12–16 blocks tall.
The top of a bamboo plant requires a light level of 9 or above to grow.

Design Decision - to not make bamboo saplings, and not make them go through a ton of transformations.
