Bug description:
  [Impact]

  When unity is in Low graphics mode (because of software rendering)
  there are still window animations and fade effects which we should get
  rid of.

  
  [Test case]

  This should apply naturally to a (virtual-)machine with no hardware
  acceleration or There are multiple ways to force low-gfx mode:

  1) Add an upstart job such as:

  cat << EOF > ~/.config/upstart/lowgfx.conf
  start on starting unity7

  pre-start script
    #initctl set-env --global UNITY_LOW_GFX_MODE=1
    initctl set-env --global LIBGL_ALWAYS_SOFTWARE=1
  end script
  EOF 

  
  2) Run unity with:
     COMPIZ_CONFIG_PROFILE=ubuntu-lowgfx

  On login unity should use opaque views (dash, switcher, launcher,
  shortcut-dialogs) with no fading and reduced effects. Windows should
  also use smaller shadows.

  
  [Regression potential]

  Some settings from unity-control-center couldn't be applied to normal
  profile. Low graphics mode might be used as normal one.
