UnityEngine C# API A..C array parameters
// just going through Data/Managed/UnityEngine.xml in Unity 2023.1.0a22, letters A to C,
// searching for "[]" finds these public APIs that take arrays as parameters. Then next to
// them I looked whether they have a List<> or NativeArray<> variants. Some do have List<>,
// very few have native array. Most of them would be good candidates to take a Span<T>,
// in some cases that might reduce the need for also having "an integer offset and number of items"
// arguments that some (minority) of them do.
// This is only A..C so far, or maybe like 10% of the UnityEngine.xml API. UnityEditor.xml probably
// has a ton of similar ones :)
