This change is to help with an attempt to allow the Context type in wgpu to be swappable at runtime. In order to do that, the functions provided by Context and it's associated types need to be object safe. Instead of passing a impl trait that combines both HasRawWindowHandle and HasRawDisplayHandle, we seperate the types into their RawDisplayHandle and RawWindowHandle parts internally to reduce some of the hal implementation code mess.
wgpu player
This is an application that allows replaying the wgpu workloads recorded elsewhere. It requires the player to be built from
the same revision as an application was linking to, or otherwise the data may fail to load.
Launch as:
play <trace-dir>
When built with "winit" feature, it's able to replay the workloads that operate on a swapchain. It renders each frame sequentially, then waits for the user to close the window. When built without "winit", it launches in console mode and can replay any trace that doesn't use swapchains.
Note: replaying is currently restricted to the same backend, as one used for recording a trace. It is straightforward, however, to just replace the backend in RON, since it's serialized as plain text. Valid values are: Vulkan, Metal, Dx12, and Dx11.
