IKRot

Transforms the input image using two points that 'look at' each other.
It's like using just 2 points of a corner pin but with more options:

You can enable/disable transform, rotation and scale and append tracking data without compromising manual transformation.

Longer demo: https://vimeo.com/341203118

All code is contained in the node so You can 'copy to group' without problems if You want a group instead of a gizmo.

Tested only with Nuke11.2 and 11.3 but should work for older version as well.
