Add 'plantlike_rooted' drawtype
Browse files Browse the repository at this point in the history 
Useful for underwater plants.
Node consists of a base cube plus a plantlike extension that can pass through
liquid nodes above without creating air bubbles or interfering with liquid flow.
Uses paramtype2 'leveled', param2 defines height of plantlike extension.

* `raillike`
* `nodebox` -- See below. (**Experimental!**)
* `mesh` -- use models for nodes
* `plantlike_rooted`

`*_optional` drawtypes need less rendering time if deactivated (always client side).
