Bug description:
  [Test Case]
  Performance fix - only way of testing is performing the benchmarking steps again to check if there is improvement.

  [Regression Potential]
  No obvious regression potential.

  Original description:

  I've been running a callgrind session trying to figure out how we
  could speed up opening the dash and it turned out that especially the
  first time the dash is opened, we spend more than 25% of time in
  QueueDraw - see the attached callgrind profile (best viewed with
  kcachegrind).

  Attaching also a simple unity patch that was used to collect the data
  + the command line was `valgrind --tool=callgrind --instr-atstart=no
  --collect-atstart=no compiz --replace ccp`.
