* Represents a vector or matrix that is composed from other expressions, such as
* `half3(pos.xy, 1)` or `mat3(,, 0, 0, 1)`
* These can contain a mix of scalars and aggregates. The total number of scalar values inside the
* constructor must always match the type's slot count. (e.g. `pos.xy` consumes two slots.)
* The inner values must have the same component type as the vector/matrix.
