Box widget doesn't respect homogenous=False, expand=False, or fill=False

[Artanis]

According to the docs, homogenous=False should allow child widgets to have different amounts of space allocated to them. This should be according to how much space they need. Instead, each child is allocated a similar amount of space.

Just as well, expand=False, which informs the Box that the widget doesn't want any extra space, is ignored, as is fill=False, resulting in all the extra space being allocated to the child widget.
