OrcaSlicer/src/slic3r/GUI/Mouse3DController.cpp
bubnikv 25d58faaad WIP: Windows specific 3Dconnexion using WM_INPUT. 
This implementation works with the 3DConnexion driver (sic!)
if PrusaSlicer.xml is stored into c:\Program Files\3Dconnexion\3DxWare\3DxWinCore64\Cfg\

The implementation is inspired with Blender, see code inside WITH_INPUT_NDOF blocks.
