Enable floatBlend for D3D9 Although according to https://docs.microsoft.com/en-us/windows/desktop/direct3ddxgi/format-support-for-direct3d-feature-level-9-1-hardware D3D9 doesn't have full blending capability for RGBA32F. But turns out it could provide correct blending result in reality. As a result of some regression reports by client app, we decided to turn floatBlend on for D3D9. I tried to make a native D3D9 program to detect float blending capability. But turns out it needs quite some effort on Win10 for a D3D newbie. Considering the fact that D3D9 backend is not fully passing conformance test anyway. I don't think it worth the effort. Seems to be okay to just turn it on.
