QNX: Enable threaded OpenGL rendering on QNX
The only complicated aspect to this was deferring EGLsurface
re-creation as a result of window geometry changes (e.g. when we
receive an orientation change event). To allow this to be done
in a controlled way we defer the surface manipulation until the
next call to QQnxGLContext::makeCurrent().
