Update()

Updates the GrowFX internal caches and viewport display to account for all the changes made by other functions in this kit.

NewSeed()

Generate a new random seed.

addPath [ <path_name_string> ]

Adds a new path and returns the index of path, 0 if it failed.

addDistributor <path_index_integer> \
( #distr | #point | #path | #pathpos | #surface ) \
[ <name_string> ]

Adds a new distributor to the indexed path, where <path_index_integer> is the index of the path. The 2 argument specifies the type of the distributor. Returns true if the addition was successful, false if it failed.
