+    TAPL tests - make all apps in overview checks less fragile.
+    
+    Tests that check for all apps in overview mode were only checking for

+    uses all apps.
+    
+    Centralize the check for all apps.

+    Update mEndRect when closing ArrowPopup
+    
+    Generally mEndRect is still correct from when we set it in
+    animateOpen(), but there are cases where it is no longer valid and
+    should be recomputed in animateClose(). For example, if you dismiss
+    notifications, the height of the popup changes between opening and
+    closing it.
+    
+    Test: Long press an icon with a notification dot, dismiss all
+    notifications from the popup and then close the popup. The shadow
+    follows the outline of the popup, instead of extending well below it.

+
+    Fixes incorrect FromFolderLabelState in clearcut log when updating folder label.
+    
+    Bug description: When folder label is updated from a suggested label to a custom label,
+    EditFolderLabelEvent log expected to have FromFolderLabelState = FROM_SUGGESTED.
+    Currently FromFolderLabelState is logged as FROM_CUSTOM in such scenarios.
+    
+    Root cause: Folder label state is decided based on whether IME has entered into compose mode while editing.
+    This works fine for initial folder creation and also updated to non-empty label(to both custom or suggested).
+    But when folder is edited from suggested to empty label, its internal state changes from SUGGESTED to CUSTOM as expected.
+    Later when empty label is updated to suggested again, its internal state remains custom forever.
+    
+    Fix: Instead of setting folder's internal state based on IME's compose mode, comparing actual folder label with suggestions
+    and set it to SUGGESTED if any suggestion matches else CUSTOM.

+    Render user's actual workspace in ThemePicker preview (Part 3)
+    
+    go/grid-migration-preview
+    
+    With this change, we can see actual grid migration in wallpaper preview.
+    
+    The approach here: we use a tmp table (favorites_preview) here specifically for this preview (to write off the migration results), and load from this tmp table workspace items if migration is necessary and successful. Otherwise, we load from the current workspace.
+    
+    UPDATED: this change should be completely compatible with the new multi-db grid migration algorithm. Here is why
+    1. In LauncherPreviewRender#renderScreenShot, I added a check to decide which grid migration preview method we should call. Once v2 preview method is implemented, it should be integrated with other parts of this change perfectly (the reason will be mentioned below).
+    2. While we have multiple DBs, mOpenHelper in LauncherProvider always points to the current db we are using. Queries using CONTENT_URI is routed to whatever DB mOpenHelper points to, so it works perfectly to directly operate on CONTENT_URI even when we use multi-db underneath the hood.
+    3. With 1 and 2 mentioned, I believe in order for this preview change to support multi-db, we only need to implement the V2 grid migration algorithm. Because most of what we are doing in this change is wrapped in GridSizeMigrationTask, it's perfectly safeguarded.

+
+    Always update clip rect before applying surface params
+    
+    Previously, we were only updating the clip rect when params.currentRect
+    == null, meaning the clip would be stale once the caller started
+    providing its own rect (e.g. when swiping to home).
+    
+    Also fix some visual jumps when swiping home, all caused by running the
+    transform progress from 0 to 1 instead of starting at whatever the
+    progress was before ending the gesture, e.g.:
+    - When swiping to home without animating into an icon, the corner radius
+      was set back to the window corner radius.
+    - Before this change, the clip didn't update throughout the animation,
+      making the window slightly bigger than the floating icon view; after
+      this change, the clip jumped to show the insets again before clipping
+      back down during the home animation.

+
+    Clean up AppWindowAnimationHelper and TransformParams
+    
+    AppWindowAnimationHelper and TransformParams were being very tightly
+    intertwined, to the point that you really had to understand subtle
+    nuances of both in order to get a desired behavior. This makes making
+    changes really difficult, because there are lots of "traps" to know
+    about and navigate. To help alleviate this burden, cleaned up some of
+    these traps and give AWAH and TP distinct roles:
+    - A caller who needs to animate an app window needs both AWAH and TP.
+      TP defines specific parameters of how the app window should be
+      controlled, and AWAH simply reads from TP in order to provide the
+      desired behavior.
+    - Only the caller should write to TP; AWAH should no longer change
+      anything in a TP that is passed to it. For instance, instead of
+      repurposing TP.currentRect, AWAH now has its own mCurrentRect to
+      update based on passed parameters.
+    - TP is a very basic class that just holds various values that callers
+      can set one at a time. The order should not matter (setting one value
+      will never set another one), and defaults make sense.
+    - Commented the setter methods in TP so developers shouldn't have to
+      follow the code to see how they are used.

+    Updating logcat reading logic
+    
+    Start a thread to read logcat synchronusly instead
+    of back-tracking at the end of the test
+    
+    Also:
+    * Reusing the same logcat process for all checks. This eliminates
+    reading the log from its start for every gesture. We don’t kill that
+    process at the end, and don’t stop the thread. I’ve verified that
+    “am instrument” doesn’t hang, and the logcat process gets automatically
+    killed after the test process exits.
+    * Not using mStarted latch, as there is no need to wait until the reader
+    reaches the start mark.

+    Makes all ArrowPopups AccessibilityTargets.
+    
+    This currently includes the menu that pops up when
+    long pressing an app icon in Launcher or Search, or
+    long pressing Smartspace. Previously, only the menu
+    for Launcher apps grabbed accessibility focus after
+    the open animation completed, and now all three do.
