/**
 * "Possibly evaluated value" is an intermediate stage in the evaluation chain for both paint and layout property
 * values. The purpose of this stage is to optimize away unnecessary recalculations for data-driven properties. Code
 * which uses data-driven property values must assume that the value is dependent on feature data, and request that it
 * be evaluated for each feature. But when that property value is in fact a constant or camera function, the calculation
 * will not actually depend on the feature, and we can benefit from returning the prior result of having done the
 * evaluation once, ahead of time, in an intermediate step whose inputs are just the value and "global" parameters
 * such as current zoom level.
 *
 * `PossiblyEvaluatedValue` represents the three possible outcomes of this step: if the input value was a constant or
 * camera expression, then the "possibly evaluated" result is a constant value. Otherwise, the input value was either
 * a source or composite expression, and we must defer final evaluation until supplied a feature. We separate
 * the source and composite cases because they are handled differently when generating GL attributes, buffers, and
 * uniforms.
 *
 * Note that `PossiblyEvaluatedValue` (and `PossiblyEvaluatedPropertyValue`, below) are _not_ used for properties that
 * do not allow data-driven values. For such properties, we know that the "possibly evaluated" result is always a constant
 * scalar value. See below.
