Detailed Description

Utility class for synchronized transfer of a texture between two D3D devices

This class is used to copy a texture from one device to another device. This is implemented using a shared texture, along with keyed mutexes to synchronize access to the texture.

This is needed because the source and destination may use different D3D devices, for example when copying a decoded frame owned by FFmpeg or the Windows Media Foundation media engine into a texture usable by RHI.
