Description
In many places we've added C-style casts to silence compiler warnings, for example when truncating a size_t to an int when we know the size_t is a small struct. Such casts are inherently risky, because they effectively disable useful compiler warnings. We should add a form of cast that checks at runtime that a truncation does not overflow.
