  *
  * Available since API level 30.
  *
+ * Starting in API level 31, it can be used to decode all of the frames of an
+ * animated image (i.e. GIF, WebP) using new APIs. Internally,
+ * AImageDecoder keeps track of its "current frame" - that is, the frame that
+ * will be decoded by a call to AImageDecoder_decodeImage. At creation time, the
+ * current frame is always the first frame, and multiple calls to this method
+ * will each decode the first frame. {@link AImageDecoder_advanceFrame} advances
+ * the current frame to the following frame, so that future calls to this method
+ * will decode that frame. Some frames may update only part of the image. They
+ * may only update a sub-rectangle (see {@link
+ * AImageDecoderFrameInfo_getFrameRect}), or they may have alpha (see
+ * {@link AImageDecoderFrameInfo_hasAlphaWithinBounds}). In these cases, this
+ * method assumes that the prior frame is still residing in the |pixels| buffer,
+ * decodes only the new portion, and blends it with the buffer. Frames that change
+ * the entire |pixels| buffer are "independent", and do not require the prior
+ * frame to remain in the buffer. The first frame is always independent. A
+ * sophisticated client can use information from the {@link AImageDecoderFrameInfo}
+ * to determine whether other frames are independent, or what frames they rely on.
+ *
+ * If the current frame is marked {@link ANDROID_IMAGE_DECODER_DISPOSE_OP_PREVIOUS},
+ * AImageDecoder_decodeImage will store the |pixels| buffer prior to decoding
+ * (note: this only happens for the first in a string of consecutive
+ * ANDROID_IMAGE_DECODER_DISPOSE_OP_PREVIOUS frames). After advancing to the
+ * following frame, AImageDecoder_decodeImage will restore that buffer prior to
+ * decoding that frame. This is the default behavior, but it can be disabled
+ * by passing false to {@link AImageDecoder_setInternallyHandleDisposePrevious}.
+ *
+ * Ignoring timing information, display, etc, a client wishing to decode all
+ * frames of an animated image may conceptually use code like the following:

+ * Note that this only attempts to track the headroom of slow-moving sensors, such as
+ * the skin temperature sensor. This means that there is no benefit to calling this function
+ * more frequently than about once per second, and attempted to call significantly
+ * more frequently may result in the function returning {@code NaN}.
+ *
+ * In addition, in order to be able to provide an accurate forecast, the system does
+ * not attempt to forecast until it has multiple temperature samples from which to
+ * extrapolate. This should only take a few seconds from the time of the first call,
+ * but during this time, no forecasting will occur, and the current headroom will be
+ * returned regardless of the value of {@code forecastSeconds}.
+ *
+ * The value returned is a non-negative float that represents how much of the thermal envelope
+ * is in use (or is forecasted to be in use). A value of 1.0 indicates that the device is
+ * (or will be) throttled at {@link #ATHERMAL_STATUS_SEVERE}. Such throttling can affect the
+ * CPU, GPU, and other subsystems. Values may exceed 1.0, but there is no implied mapping
+ * to specific thermal levels beyond that point. This means that values greater than 1.0
+ * may correspond to {@link #ATHERMAL_STATUS_SEVERE}, but may also represent heavier throttling.
+ *
+ * A value of 0.0 corresponds to a fixed distance from 1.0, but does not correspond to any
+ * particular thermal status or temperature. Values on (0.0, 1.0] may be expected to scale
+ * linearly with temperature, though temperature changes over time are typically not linear.
+ * Negative values will be clamped to 0.0 before returning.

+ * @param manager The manager instance to use.

+// Fixed-capacity, statically allocated counterpart of std::vector. Like std::array, StaticVector
+// allocates contiguous storage for N elements of type T at compile time, but stores at most (rather
+// than exactly) N elements. Unlike std::array, its default constructor does not require T to have a
+// default constructor, since elements are constructed in place as the vector grows. Operations that
+// insert an element (emplace_back, push_back, etc.) fail when the vector is full. The API otherwise
+// adheres to standard containers, except the unstable_erase operation that does not preserve order,
+// and the replace operation that destructively emplaces.
+//
+// StaticVector<T, 1> is analogous to an iterable std::optional.
+// StaticVector<T, 0> is an error.

+# FTL
+
+FTL is a template library shared by SurfaceFlinger and InputFlinger, inspired by
+and supplementing the C++ Standard Library. The intent is to fill gaps for areas
+not (yet) covered—like cache-efficient data structures and lock-free concurrency
+primitives—and implement proposals that are missing or experimental in Android's
+libc++ branch. The design takes some liberties with standard compliance, notably
+assuming that exceptions are disabled.
+
+## Tests
+
+    atest ftl_test
+
+## Style
+
+- Based on [Google C++ Style](https://google.github.io/styleguide/cppguide.html).
+- Informed by [C++ Core Guidelines](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines).
+
+Naming conventions are as follows:
+
+- `PascalCase`
+    - Types and aliases, except standard interfaces.
+    - Template parameters, including non-type ones.
+- `snake_case`
+    - Variables, and data members with trailing underscore.
+    - Functions, free and member alike.
+    - Type traits, with standard `_t` and `_v` suffixes.
+- `kCamelCase`
+    - Enumerators and `constexpr` constants with static storage duration.
+- `MACRO_CASE`
+    - Macros, with `FTL_` prefix unless `#undef`ed.
+
+Template parameter packs are named with the following convention:
+
+    typename T, typename... Ts
+    typename Arg, typename... Args
+
+    std::size_t I, std::size_t... Is
+    std::size_t Size, std::size_t... Sizes
+
+The `details` namespace contains implementation details.

+This library turns on recording of skia commands in SkiaGL version of the RE.
+The debug property defines number of milliseconds for the recording to take place.
+A non zero value turns on the recording. The recording will stop after MS specified.
+To reset the recording, set the capture_skia_ms flag to a new time. When recording
+is finished, the capture_skia_ms flag will be set to 0 to avoid circular recording.
+
+In order to allow the process to write files onto the device run:
+adb shell setenforce 0
+
+To start recording run:
+adb shell setprop debug.renderengine.capture_skia_ms 1000
+
+File will be stored in the /data/user/ directory on the device:
+adb shell ls -al /data/user/
+
+To retrieve the data from the device:
+adb pull /data/user/re_skiacapture_<timestamp>.mskp

+/**
+ * Arguments for creating an effect that applies color transformations in linear XYZ space.
+ * A linear effect is decomposed into the following steps when operating on an image:
+ * 1. Electrical-Optical Transfer Function (EOTF) maps the input RGB signal into the intended
+ * relative display brightness of the scene in nits for each RGB channel
+ * 2. Transformation matrix from linear RGB brightness to linear XYZ, to operate on display
+ * luminance.
+ * 3. Opto-Optical Transfer Function (OOTF) applies a "rendering intent". This can include tone
+ * mapping to display SDR content alongside HDR content, or any number of subjective transformations
+ * 4. Transformation matrix from linear XYZ back to linear RGB brightness.
+ * 5. Opto-Electronic Transfer Function (OETF) maps the display brightness of the scene back to
+ * output RGB colors.
+ *
+ * For further reading, consult the recommendation in ITU-R BT.2390-4:
+ * https://www.itu.int/dms_pub/itu-r/opb/rep/R-REP-BT.2390-4-2018-PDF-E.pdf
+ *
+ * Skia normally attempts to do its own simple tone mapping, i.e., the working color space is
+ * intended to be the output surface. However, Skia does not support complex tone mapping such as
+ * polynomial interpolation. As such, this filter assumes that tone mapping has not yet been applied
+ * to the source colors. so that the tone mapping process is only applied once by this effect. Tone
+ * mapping is applied when presenting HDR content (content with HLG or PQ transfer functions)
+ * alongside other content, whereby maximum input luminance is mapped to maximum output luminance
+ * and intermediate values are interpolated.

+ * We will see both launcher and wallpaper in that list.
+ * Once the interaction with a particular set of connections starts, no new logs will be printed
+ * until the set of interacted connections changes.
+ *
+ * The following items are skipped, to reduce the logspam:
+ * ACTION_OUTSIDE: any windows that are receiving ACTION_OUTSIDE are not logged
+ * ACTION_UP: any windows that receive ACTION_UP are not logged (for both keys and motions).
+ * This includes situations like the soft BACK button key. When the user releases (lifts up the
+ * finger) the back button, then navigation bar will inject KEYCODE_BACK with ACTION_UP.

+# ANR detection in InputDispatcher #
+
+'ANR' means 'application not responding'. This is an event that gets triggered when the system thinks that an application is too slow to respond. A dialog may pop up because of an ANR event. ANRs can be triggered by multiple systems within Android.
+
+In InputDispatcher, ANRs are raised in 2 cases:
+
+1. An event was sent to a connection, and the response was not received within a certain timeout.
+2. The application did not have a focused window, and an input event that requires focus was generated by the user.
+
+Let's consider each of these cases.
+
+## 1. Application does not respond to an input event that was sent to it. ##
+
+The most common case is when an application does not respond to input that dispatcher sent to it. Typically, it means an application is performing a long operation on its UI thread.
+
+When the event is being dispatched to an application, the normal flow is: `mPendingEvent` → `connection.outboundQueue` → `connection.waitQueue`.
+
+Every dispatch cycle, InputDispatcher will check all connections to see if any are unresponsive. To determine whether an app is not responding, we look at the oldest entry in the `waitQueue`. If the entry sits in the `waitQueue` past `entry.timeoutTime`, we trigger an ANR.
+
+
+### Checking if a connection is unresponsive ###
+
+When a dispatch entry is sent to the app, its `deliveryTime` and `timeoutTime` fields are populated. The `deliveryTime` is the time that the event is delivered to the app. This is simply the current time inside `publishMotionEvent`. The `timeoutTime` is the time when this entry would be considered overdue. At that time, the ANR process would start for this connection.
+
+Most connections are associated with a window, and each window may have a custom timeout time. To calculate the timeout time of a specific event, simply add the `window.dispatchingTimeout` to the current time. In case where there is no associated window, such as gesture monitors, use the default dispatching timeout which is defined in `android.os.InputConstants.DEFAULT_DISPATCHING_TIMEOUT_MILLIS`.
+
+The `timeoutTime` field of the `DispatchEntry` is needed because the window associated with a specific connection may change its timeout time. Therefore, entries sent prior to the timeout change would need to follow the previous timeout value. If a window timeout changes, it only affects new events being dispatched, and does not alter the timeout times of events already sent to the app.
+
+For example, if an application is being debugged, the ActivityManager may want to increase the timeout time for a window to prevent the ANR dialog from appearing or the app from getting killed.
+
+Looping through `waitQueue`s of all connections on every dispatch cycle could be costly. To improve this, we introduced the `AnrTracker` class.
+
+`AnrTracker` uses a multiset (a set that allows duplicate entries) to keep track of the next time a dispatch entry would become out of date. Duplicate entries are allowed because there may be two events with an identical timeout time. This is unlikely to happen in practice today, but is possible if the window timeouts are different or if the device has a high input report rate or a low clock resolution.
+
+On each dispatch cycle, InputDispatcher checks `AnrTracker` for the nearest timeout value. If the nearest timeout value is in the past, InputDispatcher will trigger the ANR for the corresponding connection.
+
+When an application sends a response for a particular dispatch entry, that entry is removed from the connection's `waitQueue`, and it is also removed from the `AnrTracker`. During normal operation, the entries are removed from `AnrTracker` quickly.
+
+
+### How to test ###
+
+In order to test this behaviour, you can create an application that calls `SystemClock.sleep` while handling a click event.
+
+When this happens, the expectation is that the ANR dialog will come up within a short period of sending an input event (typically 5 seconds). While the app is not responding, it is expected that touches on other applications and gesture monitors still continue to work.
+
+
+## 2. Application does not have a focused window, and a focused event comes in ##
+
+This is a legacy behaviour that we are maintaining inside InputDispatcher. When an application is launched, WindowManager calls `setFocusedApplication` to tell InputDispatcher that there is a focused application. This is used by InputDispatcher purely for ANR and debugging purposes.
+
+After launching, an application may not add a focused window. This could be either due to a bug in WindowManager or in the app.
+
+The legacy behaviour in this situation is as follows: touches will continue to function normally, without causing an ANR. If there is a focused event, however, it would require a focused window to be dispatched. InputDispatcher will keep this focused event inside mPendingEvent until:
+
+* A focused window is added
+* Timeout occurs
+* User touches another application
+
+To keep track of this timeout, when this situation is detected initially, `mInputTargetWaitTimeoutTime` and `mAwaitedFocusedApplication` are set. When the `mInputTargetWaitTimeoutTime` expires, an ANR will be raised.
+
+
+### How to test ###
+
+Create an empty application that sets `FLAG_NOT_FOCUSABLE` on its window in `onCreate`. Touching the application's window should not cause an ANR. Sending a key event to the application, however, should cause ANR. One easy way to do this is by pressing or gesturing the BACK key. In this scenario, `adb shell dumpsys input` will reveal that there's no focused window in the current display.
+
+
+## Extending the timeout based on the response from policy ##
+
+When the policy processes the ANR notification and responds with a positive timeout, InputDispatcher marks the connection as "responsive" by setting `inputPublisherBlocked = false`. All of the entries for this connection inside AnrTracker will be modified to expire at `time = (current time) + (timeout extension returned by policy)`.
+
+If the policy wants to abort dispatch, it returns a timeout value of 0. In this case, InputDispatcher will synthesize cancel events for the connection.
+
+When an app is unresponsive, new touches do not go to the app. They get dropped with a warning log. This is done to prevent overwhelming the app with events in case it later becomes responsive.

+# Pointer Capture in InputFlinger
+
+## Introduction
+
+[Pointer Capture](https://developer.android.com/training/gestures/movement#pointer-capture) is a feature that was introduced to the Android input pipeline in Android 8.0 (Oreo). Pointer Capture can be enabled or disabled for an `InputWindow` through requests to `InputManagerService`. Enabling Pointer Capture performs the following changes related to the mouse cursor and the devices that control it:
+
+- The position of the mouse cursor is fixed to its location before Pointer Capture was enabled.
+- The mouse cursor is hidden.
+- Events from a mouse will be delivered with the source `SOURCE_MOUSE_RELATIVE`, and their `AXIS_X` and `AXIS_Y` will report relative position changes.
+- Events from a touchpad will be delivered with the source `SOURCE_TOUCHPAD`, and their `AXIS_X` and `AXIS_Y` will report the absolute position of each of the pointers on the touchpad.
+- Events from mouse and touchpad devices are dispatched to the focused `InputWindow`.
+- Events from devices that do not normally control the mouse cursor are not affected.
+
+`InputWindow`s can only gain Pointer Capture if they have window focus. If a window with Pointer Capture loses focus, Pointer Capture is disabled.
+
+## Pointer Capture pipeline in InputFlinger
+
+`InputDispatcher` is responsible for controlling the state of Pointer Capture. Since the feature requires changes to how events are generated, Pointer Capture is configured in `InputReader`.
+
+### Enabling Pointer Capture
+
+There are four key steps that take place when Pointer Capture is enabled:
+
+1. Requests to enable Pointer Capture are forwarded from `InputManagerService` to `InputDispatcher`.
+2. If the window that makes the request has focus, `InputDispatcher` enables the Pointer Capture state in `InputReader` through the `InputDispatcherPolicy`.
+3. When `InputReader` is successfully configured, it notifies `InputDispatcher` through the `InputListener` interface.
+4. `InputDispatcher` then notifies the `InputWindow` that Pointer Capture has been enabled by sending a special `CAPTURE` event through the `InputChannel`.
+
+### Disabling Pointer Capture
+
+Pointer Capture can be disabled in two ways: by a request through `InputManagerService`, and as a result of the `InputWindow` losing focus.
+
+When Pointer Capture is disabled by a request from the application, it follows the same pipeline as when Pointer Capture is enabled.
+
+#### Window loses Pointer Capture when it loses focus
+
+When an `InputWindow` with Pointer Capture loses focus, Pointer Capture is disabled immediately. The `InputWindow` receives a `CAPTURE` event through the `InputChannel`, followed by a `FOCUS` event to notify loss of focus.
+
+## Pointer Capture in `InputDispatcher`
+
+`InputDispatcher` tracks two pieces of state information regarding Pointer Capture:
+
+- `mFocusedWindowRequestedPointerCapture`: Whether or not the focused window has requested Pointer Capture. This is updated whenever the Dispatcher receives requests from `InputManagerService`.
+- `mWindowTokenWithPointerCapture`: The Binder token of the `InputWindow` that currently has Pointer Capture. This is only updated during the dispatch cycle. If it is not `nullptr`, it signifies that the window was notified that it has Pointer Capture.

+ * Launch two windows, with different owners. One window (slipperyExitWindow) has Flag::SLIPPERY,
+ * and overlaps the other window, slipperyEnterWindow. The window 'slipperyExitWindow' is on top
+ * of the 'slipperyEnterWindow'.
+ *
+ * Inject touch down into the top window. Upon receipt of the DOWN event, move the window in such
+ * a way so that the touched location is no longer covered by the top window.
+ *
+ * Next, inject a MOVE event. Because the top window already moved earlier, this event is now
+ * positioned over the bottom (slipperyEnterWindow) only. And because the top window had
+ * Flag::SLIPPERY, this will cause the top window to lose the touch event (it will receive
+ * ACTION_CANCEL instead), and the bottom window will receive a newly generated gesture (starting
+ * with ACTION_DOWN).
+ * Thus, the touch has been transferred from the top window into the bottom window, because the top
+ * window moved itself away from the touched location and had Flag::SLIPPERY.
+ *
+ * Even though the top window moved away from the touched location, it is still obscuring the bottom
+ * window. It's just not obscuring it at the touched location. That means, FLAG_WINDOW_IS_PARTIALLY_
+ * OBSCURED should be set for the MotionEvent that reaches the bottom window.
+ *
+ * In this test, we ensure that the event received by the bottom window has
+ * FLAG_WINDOW_IS_PARTIALLY_OBSCURED.
