Just a simple program to light up all detected outputs at their native
mode and respond to hotplug events.

/*
* This program is intended for testing of display functionality. It should
* allow for testing of
* - hotplug
* - mode setting
* - clone & twin modes
* - panel fitting
* - test patterns & pixel generators
* Additional programs can test the detected outputs against VBT provided
* device lists (both docked & undocked).
*
* TODO:
* - pixel generator in transcoder
* - test pattern reg in pipe
* - test patterns on outputs (e.g. TV)
* - handle hotplug (leaks crtcs, can't handle clones)
* - allow mode force
* - expose output specific controls
* - e.g. DDC-CI brightness
* - HDMI controls
* - panel brightness
* - DP commands (e.g. poweroff)
* - verify outputs against VBT/physical connectors
