Surface: Do not copy back if front and back buffer are identical It is unnecessary to copy from and to the same surface. Skipping the copy back is a huge performance improvement when using shared buffer mode and locking a rectangle of the surface. Bug: 38398135 Test: Use stylus demo and remove full-surface locking hack. Change-Id: Ie8d03468507489247ba4a4be5f0cde5960e69c16
