ID 430184 - LensDistortion node does not create features and lines correctly when using an anamorphic input

Problem summary:
When using the LensDistortion node, if you are using an anamorphic (or non-square) pixel ratio, any lines or features created will be constrained within the square pixel ratio area of the viewer.

Note: This only occurs in Nuke 12.1v1 and later versions

Customer reported version:
Nuke 12.1v1

Customer reported platform:
CentOS 7

Steps to reproduce:
1) Open Nuke.
2) Create a Checkerboard node.
3) Within the Checkerboard properties, create a new format, setting the pixel aspect ratio to 2.
​

​
4) In the Node Graph, create a LensDistortion node, connecting it to the Checkerboard node.
5) Within the LensDistortion nodes toolbar, select the Add Lines tool, and attempt to draw a line from one edge of the anamorphic footage to the other.
Result: Your points will be incorrectly placed within a predefined square pixel aspect ratio area.

​

 

Alternative steps: 
1) Open Nuke.
2) Create a Checkerboard node
3) Within the Checkerboard properties, create a new format, setting the pixel aspect ratio to 2.​
4) In the Node Graph, create a LensDistortion node, connecting it to the Checkerboard node.
5) On the LensDistortion node, open the Analysis tab and press Detect.
6) Try to click and drag one of the features (close to the edge of the image).
Result: The point will 'jump' towards the centre of the image.
