-   At a high level, this works by setting temporary parameters that are not stored
-   in the avatar's list of params, and are not conveyed to other users.  We accomplish
-   this by creating some new temporary driven params inside avatar_lad that are then driven
-   by the actual params that the user sees and sets.  For example, in the old system,
-   the user sets a param called breast bouyancy, which controls the Z value of the breasts.
-   In our new system, the user still sets the breast bouyancy, but that param is redefined
-   as a driver param so that affects a new temporary driven param that the bounce is applied
-   to.
