Provide DX12 WPF island

DX12 windows are interesting for performance (speed, latency, colors etc), bringing for instance higher colors depth, HDR, and extremely low latency for display to WPF framework.

I am doing so "by hand", involving actual c code for D3D12 and c-c# interop to provide integration, but it involve a lot of work/code for connection, sizing, injection into a XAML content, interop.

Something more standardized and implemented could be a great thing and could bring many new possibilities to WPF and to a broader audience of developers and users.
