Title:
  Screen goes blank (black) briefly during display config changes which
  don't affect the display mode

Status in Mir:
  Fix Released
Status in mir package in Ubuntu:
  New

Bug description:
  The screen goes blank (black) briefly during display config changes,
  on desktop (mesa platform). For mode changes I think this is expected,
  but it also happens for non-mode changes like screen rotation and
  probably repositioning.

  TEST CASE:
     1. Run mir_demo_server_shell
     2. Start a client you can see on screen
     3. Invoke a display config change with screen rotation: Ctrl+Alt+(arrow key)

  Expected: Instant rotation
  Observed: Screen blanks briefly before rotating.

  The blackness is very brief, but I think we can do better. By avoiding
  unnecessary destruction and reconstruction of mesa::DisplayBuffer's
  each time.
