Lightweight configurable overlay (volume/backlight/
progress/anything) bar for the X Window System (and
Wayland compositors with XWayland).
Each time a new value is read on the standard input,
it is displayed as a tv-like bar over other windows.
It then vanishes after a configurable amount of
time. A value followed by a bang '!' is displayed
using an alternate color to account for special states
(e.g. muted audio). There is also support for overflows
(when the value exceeds the maximum).
* portlint: OK (looks fine).
* testport: OK (poudriere: 12.1-RELEASE-p7, amd64).
