--- A notification background.

|
|
-- This widget holds the boilerplate code associated with the notification
|
|
-- background. This includes the color and potentially some other styling
|
|
-- elements such as the shape and border.
|
|
--
|
|
-- * Honor the `beautiful` notification variables.
|
|
-- * React to the `naughty.notification` changes.

|
-- Note that this widget is based on the `wibox.container.background`. This is
|
|
-- an implementation detail and may change in the future without prior notice.
