This CL introduces staging properties to VectorDrawable, which holds properties coming from UI thread. When staging properties are changed, they are marked dirty, and the staging properties then get pushed to RenderThread at sync point. In cases where no staging property has been changed, at sync point we sync the render thread properties back to staging properties to reflect the latest render thread animation value change. Also, update Vector Drawable bitmap only when it's dirty Bug: 27343970 Bug: 27385912 Bug: 27263667 Bug: 27927674 Bug: 27774383 Change-Id: Ia864f5400a53a08dbfb284fae581fb1aac4fff87
