Title:
  [enhancement] android hwc overlay could optimize movement of surfaces
  without buffer update

Status in Mir:
  Confirmed
Status in mir package in Ubuntu:
  New

Bug description:
  Currently, we check in the hwc code that a buffer has changed from the
  previous commit to avoid submitting the same thing to the screen
  twice. This does not factor in changes to the the screen positioning.
  If it did, we could optimize a few more scenarios using 2d
  acceleration.

  This won't  cause rendering glitches, just a bit worse performance in
  some non-critical-path scenarios.
