Explanation colors:
	Blue: System cpu usage 
	Purple: System usage if system cpu is >30%
	Yellow: User cpu usage 
	Darker yellow: User usage if system & user cpu is >50%
	Orange: User usage if system & user cpu is >70%
	White: Usage usage if system & user cpu is >99%
	Green: Nice cpu usage
        1px horizontal line: Maximum sy+us cpu of last 'avg' samples
Explanation text display:
	ni = Nice cpu usage in %
	us = User cpu usage in %
	sy = System cpu sage in %
	su = System & user cpu usage in %
	pk = Max System & user cpu usage peak of last avg. samples in %
	avg = System load average (desc. order: 1, 5 and 15 min. avg.)
