Purpose
Reasoning
Outcomes
Zero Nodes
timestamp - has no slider nodes.
Cause: A slider has no nodes.
Single Node
timestamp - has no curve points, only its start node, and so has no visible path.
Cause: A slider has only its start node and no other curve points.
Negative Length
timestamp - has negative pixel length.
Cause: A slider has a negative pixel length.
