Raph Levien 75c4b62730 Add hub abstraction ... The hub does a little better lifetime tracking of resources (so Rust-side references can be dropped), and in the future will be used for dynamic selection of backend. The migration is still a bit half-baked, as there are a bunch of Vulkan-specific types in the signatures, but it shouldn't be too much work to sort that out. Perhaps it can wait until there is a second backend though. The main motivation for this is to create image objects with lifetime tracking, one of the things required for #38.		2020-11-18 16:06:08 -08:00
