Raph Levien	6b06d249ab	Builder pattern for pipelines ... Use a builder pattern for pipelines and descriptor sets, so we can go richer without hugely complicating existing code. WIP	2020-11-24 22:11:38 -08:00
Raph Levien	47e24ec9d5	Start adding support for creating images ... This is still WIP, focused on creating image resources and making them available GPU-side. Progress toward #38	2020-11-19 16:32:29 -08:00
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
