I don't see any changes with the edges of an outline when trying to toggle on anti-aliasing:

Steps:

1. Create Shape node and set it to elipse
2. Add a padding node to add some space.  5 on each side
3. add outline node, change color, Set Width to 2
4. In outline node, toggle the "Anti Alising" (Spelling there too)

I don't see any anti-aliasing happening.  Am I using that node incorrectly?

Tried v1.15.0.1 and v 1.16rc1

Amazing tool!

I watched the trailer for the 1.15 features and see there is a FXAA node now.  Tried that and it did do what I hoped it would do.
The FXAA node doesn't have any properties like "2x, 4x, 8x etc." so I just added a second FXAA node and it cleaned up the edges even further.

So there still is a question about what the "Anti alising" button does for the Outline node.

What does the "Anti alising" (spelling is wrong in the UI) button do on the properties of the Outline Node?
