Roger Whitcomb commented on PIVOT-1031:

Add/update Javadoc. Fix some of the paint logic if the min/max or current 
values haven't been set in the component.  Set more of the colors by default in 
the skin constructor, and then remove those defaults from the sample code:

> For instance, in a monitoring application, things like CPU or disk usage can 
> nicely be displayed as a circular gauge, showing a single (the "current") 
> value.  This paradigm is currently being used in such products as Apache 
> Ambari (where it is called a "Gauge" widget).
