[vtkusers] Issue compiling VTK 8.1.2 - MinGW64 - Windows 7

[Paulo Carvalho]

Greetings, all,

    Since I got no answer, I had to do come up with a workaround.  I had to
patch the <source
root>/Rendering/OpenGL2/vtkWin32RenderWindowInteractor.cxx file (around
line 70).  The structures TOUCHINPUT and HTOUCHINPUT are incorrectly
redefined there (they're defined in winuser.h).  Since this is an error in
VTK sources, maybe the developers could patch it.
    Compiling VTK 8.1.2 in Windows 7 64 with MinGW 64.

regards,

Paulo
