"""
Desktop floating widget - CPU Cores
Uses psutil to display:
CPU usage on each individual core
Information is updated once a second and is shown as an area graph that scrolls
CPU usage of each individual core
CPU utilization is updated every 500 ms by default
Utiliziation is shown as a scrolling area graph
To achieve a "rainmeter-style" of window, these featurees were used:
An alpha-channel setting of 0.8 to give a little transparency
No titlebar
Grab anywhere, making window easy to move around
