A child is now known by its key, or by its place among the children with no
key. One whose identity was there before keeps its control, and the
controls are put in the new order by moving only those out of place. So a
list that is sorted, or has an item put in front, keeps its controls.
Text areas, sliders, progress bars, dropdowns, images, grids with cells and
spans, and scroll views. A grid's sizes are .NET properties and not
Avalonia's, so they are set by a setter of their own. A text is centred in
its height, so a label lines up with the control beside it.

A program is a model, an update and a view. A view is a Bjolang value; an
event finds its message in the view its control was last given, and the next
view is compared with the last so only what differs is changed. Controls are
made with plain constructors and changed with SetValue, so nothing is
subclassed, and a program never names an Avalonia type.
Text, button, text input, checkbox, column and row. tests/app.bjo drives an
app through its real controls with no window.
