Open requested to merge wip/exalm/wrapbox into main
A box-like container that can wrap widgets.
Background: Palette has a few in exalm/patterns#24 and exalm/patterns#25
Minimum/natural policy switcher
Clean up the code wrt overflows (situations where 0 widgets fit into a line and we squeeze 1 and let it go out of bound)
CC @jwestman though this one isn't related to that little widget we made long time ago. Still might be useful for similar situations
