Title:
  [regression] mir_demo_client_multiwin is displayed with obviously
  wrong colours

Status in Mir:
  Fix Committed
Status in “mir” package in Ubuntu:
  Triaged

Bug description:
  I just noticed client-provided alpha is not being blended correctly
  and mir_demo_client_multiwin looks significantly different now to how
  it always did up to around June. The resulting colours are additive
  (brighter) when clients with alpha overlap each other.

  Test case: Run mir_demo_client_multiwin in mir_demo_server_shell
  Expected: The pure red/green/blue regions should be darkened by their high transparency and the grey background behind them.
  Observed: The pure red/green/blue regions are full brightness, despite having opacity of only 0x50 (0.31f) in front of a grey background.
