"""Support for simplified access to data on nodes of type omni.graph.ui_nodes.LockViewportRender

Locks and unlocks viewport render. Viewport render is frozen at the frame when it is locked, while computation and UI update
are still executed as normal. It fades out back to the current frame when it is unlocked, two output execution attributes
- fadeStarted and fadeComplete - will be triggered separately during the fading progress. The node manages the lock state
for its target viewport and takes action according to the lock state when an input execution attribute is triggered. A node
is able to unlock the target viewort only if it has locked the target viewport.
