* Backlight module built using the RandR X extension.
*
* This is built as a replacement for the old backlight
* module that was set up using with inotify watches listening
* for changes to the raw file handle.
*
* This module is a lot faster, it's more responsive and it will
* be dormant until new values are reported. Inotify watches
* are a bit random when it comes to proc-/sysfs.
*
* TODO: Implement backlight configuring using scroll events
