VectorTracker

This is a tracker gizmo that uses vector information rather than image data to track points. This us useful for certain tracking jobs that are otherwise hard to accomplish. Think of shots that constantly shift focus, or tracks on objects that deform.
This gizmo works with both classic nuke vectors or smartvector data.

Simply render out either classic nuke vectors or smartvectors, and use this tool to generate tracker points. you can try using a VectorGenerator node to generate live vectors instead, but due to the way nuke and python sample image data this wont always work.
the poinsts are exported to a regular Tracker node.
