The frontend owns the window and presents, so the D3D11, D3D12 and Vulkan backends draw their picture into a FrameOutput, a render target the frontend reads where it is, rather than a swap chain. D3D11 hands over one texture at pixel shader slot 0. D3D12 negotiates version 2 of its interface and keeps one texture per sync index, handed over with the fence its picture completes on, falling back to set_texture on version 1. Vulkan keeps one image per sync index and hands it over with set_image, so the fake swap chain and the WSI calls hooked under it are gone, and the device may come without a surface. The outputs are RGBA8 and report that format to the presenter. The DXGI and Vulkan swap chains, the backends' standalone device creation and exclusive fullscreen are removed.
