Before we produce early access bundles of the Direct3D 12 pipeline, we need to set the default prism graphics pipeline order on Windows to put d3d12 as the default:

            if (PlatformUtil.isWindows()) {
                tryOrderArr = new String[] { "d3d12", "d3d", "sw" };

Otherwise, developers who download and run the D3D12 EA bundle will still get the D3D 9 pipeline without any indication that this is the case.
