Write new wallpaper files from scratch... ...rather than overwriting the existing wallpaper bitmap file "in place." If the new bitmap is smaller than the previous one, we wind up with the previous image's contents as spurious trailing file contents. Also, it means that if any wallpaper image is particularly large on disk, then we'll forever be backing up that high-water-mark amount of data every time the wallpaper is changed. The fix is to open the "write the new bitmap to disk" fd with MODE_TRUNCATE. Bug 17285333 Change-Id: I3d8708d72e316834b7ecec20386153a703efddd9
