Questions for WGPUSurface

[Kangz]

Should a WGPUTextureUsage be added to WGPUSurfaceCapabilities with guarantees like RENDER_ATTACHMENT|TEXTURE_BINDING|COPY_SRC|COPY_DST?

Where do errors go when there is no configured device on the surface? When exactly does that configure device change (unconfigure, failed calls to configure when there is already a configured device, etc). Are failures reflected in a status enum for things not linked to a device?

Is the following defined to always work without additional waits? At least on Vulkan and D3D12 it will require waiting for the GPU on WGPUSurfaceRelease:

surface = wgpuInstanceCreateSurface(sameParams);
wgpuSurfaceConfigure(surface, ...);
wgpuSurfaceRelease(surface);

surface2 = wgpuInstanceCreateSurface(sameParams);

What do we do with the extensibility and the status of GetCurrentTexture? How do we notify that a surface has been lost?

maybe merge these questions into #24 ?

for errors - see #255. I believe the resolution is to return a WGPUStatus with implementation-defined logging

for surface lost, there is WGPUSurfaceGetCurrentTextureStatus_Lost when you getCurrentTexture

for extensibility - see #261

Thank, closing in favor of these.
