TimeWarp
Changes the time at which upstream nodes are evaluated using the following formula :
upstreamFrame = frame * speed + offset
user
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
enabled
Turns the node on and off.
speed
Multiplies the current frame value.
offset
Adds to the current frame value (after multiplication with speed).
