Windows demo crashes due to "glewInit()" not being called anywhere

[Coder666]

I just got latest code and built with VS 2019 on Windows.

Running the demo fails because all of the gl function pointers are NULL, to get it running I had to add a call to glewInit() in TBRendererGL c'tor

Cheers

Thaks for the note! Would you be able to submit a patch? I dont run Windows, so have no way to test any fix.

That should do the trick.
