Dear Maintainer, The debian/tests/triangle.hlsl file was originally copied from demos/triangle.hlsl but since then the new upstream release 1.16 has added a copyright/license header which makes it SPDX-License-Identifier: LGPL-2.1-or-later AND MIT (or License: LGPL-2.1+ and Expat in Debian-speak), with the copyright holders being Microsoft and Henri Verbeet for CodeWeavers. The attached patch realigns the file from demos/triangle.hlsl bringing in the copyright/license header. Thanks, Antonio
