CFrame is the main parent window. Inside CFrame there is an m_Panel that is the parent for
the rendering window (when we render to the main window). In Windows the rendering window is
created by giving CreateWindow() m_Panel->GetHandle() as parent window and creating a new
child window to m_Panel. The new child window handle that is returned by CreateWindow() can
be accessed from Core::GetWindowHandle().
