A menu anchor: the popup's look, and how it is placed against whatever opened it.
Where UMG's MenuAnchor keeps Placement as a widget property, it lives here because it is the same kind of decision as a corner radius -- a project wants every menu to open the same way -- and because the control still exposes it per instance through the style's override bits.
The placement ENUM is not declared here: it is EDreamMenuPlacement, which belongs to UDreamLayoutContainerMenuAnchor along with the arithmetic that reads it. One enum and one set of placement maths for the layout panel and the control, so a menu opened by either lands in the same place -- and so there is nothing to keep in step when a placement is added.
