OK, I'm fine with this if you're ok to go ahead and implement the caching. It's worth noting that drivers can discard any vram backing sampler views at any time (when they're not in use), so if we have a situation where large numbers of views are gobbling up vram, the driver has the option of running though all the views and discarding their cached contents.
