A pane is a both a container and a containee area. It serves only
as a geometry management device. A
pane%
cannot be hidden or disabled like a
panel% object.
A pane% object has a degenerate placement strategy for
managing its children; it places them all in the upper left corner
and does not stretch any of them. The horizontal-pane% and
vertical-pane% classes provide useful geometry management.
