JunitTest_framework_complex fails reliably for me on current master with
assertion
assert( mpWindowContext.is() );
failing at OpenGLSalGraphicsImpl::doFlush().
I could debug it to WinOpenGLContext::ImplInit() having m_aGLWin.hDC ==
nullptr, thus ChoosePixelFormat fails. The call stack for this point is

So the question is why there's apparently an attempt to use window after
it was disposed; and how to properly prevent it.
