 *   do not keep record of our our list of bindings (which ranges were bound

 *
 * For sparse, the main feature of the miptail is that it only supports opaque
 * binds, so you either bind the whole miptail or you bind nothing at all,
 * there are no subresources inside it to separately bind. While the idea is

 * supports miptails for them, we can just trust the miptail level set by ISL
 * and things can proceed as The Spec intended.

 * could simply declare that every mip level is part of the miptail and be
