1105088 - Don't enable the D3D9 compositing backend except on Windows XP

Status: RESOLVED FIXED

(Core :: Graphics: Layers, defect)

Description

[Nicolas Silva [:nical]]

We don't support D3D9 compositing for other Windows version.
Curently if D3D11 fails to initialize or is blocklisted, we fallback to D3D9 on all Windows versions which is a problem.
