[Cuis-dev] Question about LayoutMorph and overlapping fullBoundsInOwner

[Mark Volkmann]

I'm thinking that "one ends where the next one starts" does not mean they
overlap.
I guess you could say they share a border.
I did the following to make it more clear:

box1 := BorderedBoxMorph new morphExtent: 100 at 100; borderColor: Color
yellow; borderWidth: 2.
box2 := BorderedBoxMorph new morphExtent: 100 at 100; borderColor: Color red;
borderWidth: 2.
layout := LayoutMorph newColumn addMorph: box1; addMorph: box2.
layout openInWorld.

Note how the bottom border of the top box and top border of the bottom box
are both visible.
