Class Overview
State sets are arrays of positive ints where each element
represents the state of a View (e.g. focused,
selected, visible, etc.). A View may be in
one or more of those states.
A state spec is an array of signed ints where each element
represents a required (if positive) or an undesired (if negative)
View state.
Utils dealing with state sets.
In theory we could encapsulate the state set and state spec arrays
and not have static methods here but there is some concern about
performance since these methods are called during view drawing.
