It turned out the bindless approach wouldn't work too well for my design of the sprite objects, but I don't think that's a big issue at this stage (and it seems bindless is causing problems for brush/alias rendering via renderdoc and on my versa pro). However, I have figured out how to make effective use of descriptor sets (finally :P). The actual normal still needs checking, but the sprites are currently unlit so not an issue at this stage.
