This is an internal function that is only displayed when you select the “Edit Vector Points” tool while holding down the Ctrl/Command key.

Its meaning is a bit complicated.
It was used for creating the presets of the Outline Warping path effect.
Bezier meshes are essentially distorted rectangles. And when a vector path is used as the basis for a Bezier mesh, PhotoLine usually determines the four corners of the rectangle itself. Sometimes it selects unwanted corners in the process.
With these user controls, you can select 4 points of a vector path and set them as the resulting corner points.
