+   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

+	  used as a reference point for the rest position of the body party.  This is usually
