/* sID experiment:
 *
 * Names of an actor, "Foo":
 * [Foo]
 * Metric=abc
 *
 * [ScreenSomething]
 * FooP1X=20
 * FooP2Y=30
 *
 * Graphics\Foo under p1
 *
 * We want to call it different things in different contexts: we may only want one
 * set of internal metrics for a given use, but separate metrics for each player at
 * the screen level, and we may or may not want separate names at the asset level.
 *
 * As is, we tend to end up having to either duplicate [Foo] to [FooP1] and [FooP2]
 * or not use m_sName for [Foo], which limits its use.  Let's try using a separate
 * name for internal metrics.  I'm not sure if this will cause more confusion than good,
 * so I'm trying it first in only this object.
