// Josh:
// Friction snapshots are used for the following:
//  - Making objects on NPCs phase through them after some time
//  - Something something physics damage, but that seems to work anyway... :think:
//  - Game code callback for freezing objects if too many objects (IVP performance backdoor) -- not relevant for us
//  - Disabling last portal stuff for objects after teleporting, but our trigger callbacks are robust so this game code hack doesn't seem to matter *touch wood*
//  - Something to do with changing paint powers
//  - Train physics blockers
// All in all, it doesn't seem to be *that* important, most things still work
// without it implemented.
// Right now, we do not have an efficient way to implement this with Jolt.
// Hence it is just stubby.
