RoosterDragon bcfaa44d66 Amortize allocations when sorting renderables. ...

Using OrderBy provides a stable sort, but internally allocates a buffer every time for storing the sort keys. We'd like to avoid this allocation, but we also can't directly use Array.Sort/Span.Sort as these are unstable sorts.

By calculating sort keys with the item index embedded, we can ensure a stable sorting result whilst being able to reuse the buffer for the sort keys across future calls.
