This will cause us to use WARP for composition on systems with Direct3D 11 when hardware acceleration is blacklisted or we're unable to find a powerful enough graphics card. It also allows us to force WARP on, in that situation WARP will also be used for Direct2D content rendering if Direct2D is enabled. Essentially this will ensure all systems running Windows 7 or higher always use D3D11 as their composition backend.
