Success on windows10

My Configurations:

• VS2017
• CMake 3.15.7
• CUDA 10.2
• Qt 5.15.13

Code modification:

libvis/opengl_context_qt.cc @ 81:

RunInQtThreadBlocking([&]() { surface = new QOffscreenSurface(); surface->setFormat(context->format()); surface->create(); });

P.S. You'd better enable large addresses for x86 version.
