Rather than bloat the `background` container with another 1k lines,
a new container is added. The goal is to implement CSS-style slicing
for the background images. The container also allows to place
generic widgets on each sides and corners of the container.
The main use case for this container is to replace the old
`awful.titlebar` API with `awful.decoration`. That new module will
allow a central client widget to be surrounded by widgets rather than
have 4 separate drawing areas. The border container is designed to
make complex border+titlebar setup trivial.
It should be called "align", but the name is already taken
It doesn't use awful.placement because it would break the dependency
graph.
Some cases previously required 2 wibox.layout.align layouts,
one for each axis. This is massively overkill to simply place
a widget at the center of a larger area.
It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.
