FBO textures are not preserved after suspend. For this reason we should
redraw the launcher on resume. This is a bug in Unity, not in the Nvidia
driver.
According to Jason Smith, we should call QueueDraw() (in Unity) to
redraw the launcher on resume. The main problem here is that, as far as
I know, there's no such thing as a handler which reinitialises Unity's
components on resume.
