Instead of trying to cram all descriptors into one large array and only binding it at the start, we now keep 1 descriptor set per image+sampler combo and just rebind it every time we switch textures. This is the very dumb solution that essentially maps to what GL does, but the performance impact is negligible compared to the complicated dance we were attempting before.
