Each Eq render thread has its own display connection and GL context. Off-screen FBO windows need to call glXMakeCurrent, which requires a window ID. Hence the hack to have an invisible window to make the context current and then bind the render FBO. AGL for example does not require this, since aglMakeCurrent only takes a GL context.
