As of c920ecc, the scenegraph DLL can be cross-built (including on Windows, via the Windows Subsystem for Linux).
Even so, users uncomfortable with the command-line would prefer to build the scenegraph DLL in the Visual Studio IDE.
Scenegraph builds in VS 2008 (an ancient, paid product), but the project has never been modernized. It would be great to get it building in VS 2022 Community Edition.
