Expand description
Layout-related data.
The View contains Rows and each Row contains Buttons.
They carry data relevant to their positioning only,
except the Button, which also carries some data
about its appearance and function.
The layout is determined bottom-up, by measuring Button sizes,
deriving Row sizes from them, and then centering them within the View.
That makes the View position immutable,
and therefore different than the other positions.
Note that it might be a better idea
to make View position depend on its contents,
and let the renderer scale and center it within the widget.
