* player could actually view all banners long enough to transition to them
* all in the course of one song select screen.
*
* If a texture is already loaded with a different policy, loading it again with
* Default is normal; keep the original policy. Other cases generally shouldn't
* happen, so warn and keep the original policy.
* Policy priority is in the order CACHED, VOLATILE, DEFAULT. Textures that are
* loaded DEFAULT can be changed to VOLATILE and CACHED; VOLATILE textures can only
* be changed to CACHED. CACHED flags are normally set explicitly on a per-texture
* basis. VOLATILE flags are set for all banners, but banners which are explicitly
* set to CACHED should stay CACHED. Finally, all textures, when they're finally used,
* are loaded as NORMAL, and that should never override.
