Detailed Description

Converts an NV12 or P010 D3D11 texture into a BGRA8 texture on the same D3D11 device, using the fixed-function ID3D11VideoProcessor. Single-plane output is required for import into non-D3D11 QRhi backends (see QWindowsD3D11RhiTextureImporter). HDR input is tone-mapped to SDR by the processor; the output is always 8-bit BGRA8.
