[PyQt] Using OpenGL in PyQt on Windows

[Guðjón Guðjónsson]

Hi Alan and Phil

OpenGL support in Virtualbox is experimental and disabled by default.
See section 4.5 in:
https://www.virtualbox.org/manual/ch04.html

I ran into the problem myself with an instrument with a control
program requiring OpenGL. I finally
got it working with Wine but I haven't tried enabling OpenGL in Virtualbox.
