Because layout properties are not transitionable, they have a simpler representation and evaluation chain than
paint properties: PropertyValues are possibly evaluated, producing possibly evaluated values, which are then
fully evaluated.
Layout stores a map of all (property name, PropertyValue) pairs for layout properties of a
given layer type. It can calculate the possibly-evaluated values for all of them at once, producing a
PossiblyEvaluated instance for the same set of properties.
