coverage map profile UI inconsistency

[NotMyFault]

When you add nodes to the default linear coverage map (without moving them), the anti-aliasing rendering changes every time despite just added at the already existing (linear) curve.

This does not make any sense at all.

To reproduce

1. create new document of low resolution (20x20px)
2. add vector shape of 1/4th of document dimension
3. rotate by 20 degree
4. open blend range UI (cog wheel)
5. open coverage map UI
6. recognize diagonal line
7. add node exactly on line, in the middle of of last two right side existing nodes
8. repeat several times. and inspect how rendering changes. To toggle, delete node by right-clicking node.

Despite all nodes added exactly on existing curve, and not changing nodes or curve in any way, the rendering differs every time.

Perfect example of "what you see is not what you get".

The file is high res to include screenshots of coverage map. Pleas start with new doc in low resolution.

bump. bug still present in V2.

And despite my original assumption, it I snot only a UI issue, but affects the rendering.
