view entity. We won't be able to retain render phases from frame to frame if the keys are unstable. It's not as simple as simply keying off the main world entity, however, because some main world entities extract to multiple render world entities. For example, directional lights extract to multiple shadow cascades, and point lights extract to one view per cubemap face. Therefore, we key off a new type, `RetainedViewEntity`, which contains the main entity plus a *subview ID*. This is part of the preparation for retained bins.
