+ * automatically. However, app still needs to call {@link ACameraCaptureSession_close} on previous
+ * session. Otherwise the resources held by previous session will NOT be freed.</p>
+ *
+ * <p>The active capture session determines the set of potential output {@link ANativeWindow}s for
+ * the camera device for each capture request. A given request may use all
+ * or only some of the outputs. Once the ACameraCaptureSession is created, requests can be
+ * submitted with {@link ACameraCaptureSession_capture} or
+ * {@link ACameraCaptureSession_setRepeatingRequest}.</p>
+ *
+ * <p>Often the {@link ANativeWindow} used with this method can be obtained from a <a href=
+ * "http://developer.android.com/reference/android/view/Surface.html">Surface</a> java object by
+ * {@link ANativeWindow_fromSurface} NDK method. Surfaces or ANativeWindow suitable for inclusion as a camera
+ * output can be created for various use cases and targets:</p>
+ *
+ * <ul>
+ *
+ * <li>For drawing to a
+ *   <a href="http://developer.android.com/reference/android/view/SurfaceView.html">SurfaceView</a>:
+ *   Once the SurfaceView's Surface is created, set the size
+ *   of the Surface with
+ *   <a href="http://developer.android.com/reference/android/view/SurfaceHolder.html#setFixedSize(int, int)">
+ *    android.view.SurfaceHolder\#setFixedSize</a> to be one of the PRIVATE output sizes
+ *   returned by {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}
+ *   and then obtain the Surface by calling <a href=
+ *   "http://developer.android.com/reference/android/view/SurfaceHolder.html#getSurface()">
+ *   android.view.SurfaceHolder\#getSurface</a>. If the size is not set by the application, it will
+ *   be rounded to the nearest supported size less than 1080p, by the camera device.</li>
+ *
+ * <li>For accessing through an OpenGL texture via a <a href=
+ *   "http://developer.android.com/reference/android/graphics/SurfaceTexture.html">SurfaceTexture</a>:
+ *   Set the size of the SurfaceTexture with <a href=
+ *   "http://developer.android.com/reference/android/graphics/SurfaceTexture.html#setDefaultBufferSize(int, int)">
+ *   setDefaultBufferSize</a> to be one of the PRIVATE output sizes
+ *   returned by {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}
+ *   before creating a Surface from the SurfaceTexture with <a href=
+ *   "http://developer.android.com/reference/android/view/Surface.html#Surface(android.graphics.SurfaceTexture)">
+ *   Surface\#Surface(SurfaceTextrue)</a>. If the size is not set by the application, it will be set to be the
+ *   smallest supported size less than 1080p, by the camera device.</li>
+ *
+ * <li>For recording with <a href=
+ *     "http://developer.android.com/reference/android/media/MediaCodec.html">
+ *     MediaCodec</a>: Call
+ *   <a href=
+ *     "http://developer.android.com/reference/android/media/MediaCodec.html#createInputSurface()">
+ *     android.media.MediaCodec\#createInputSurface</a> after configuring
+ *   the media codec to use one of the PRIVATE output sizes
+ *   returned by {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}.
+ *   </li>
+ *
+ * <li>For recording with <a href=
+ *    "http://developer.android.com/reference/android/media/MediaRecorder.html">
+ *    MediaRecorder</a>: Call
+ *   <a href="http://developer.android.com/reference/android/media/MediaRecorder.html#getSurface()">
+ *    android.media.MediaRecorder\#getSurface</a> after configuring the media recorder to use
+ *   one of the PRIVATE output sizes returned by
+ *   {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}, or configuring it to use one of the supported
+ *   <a href="http://developer.android.com/reference/android/media/CamcorderProfile.html">
+ *    CamcorderProfiles</a>.</li>
+ *
+ * <li>For efficient YUV processing with <a href=
+ *   "http://developer.android.com/reference/android/renderscript/package-summary.html">
+ *   RenderScript</a>:
+ *   Create a RenderScript
+ *   <a href="http://developer.android.com/reference/android/renderscript/Allocation.html">
+ *   Allocation</a> with a supported YUV
+ *   type, the IO_INPUT flag, and one of the YUV output sizes returned by
+ *   {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS},
+ *   Then obtain the Surface with
+ *   <a href="http://developer.android.com/reference/android/renderscript/Allocation.html#getSurface()">
+ *   Allocation#getSurface}</a>.</li>
+ *
+ * <li>For access to RAW, uncompressed YUV, or compressed JPEG data in the application: Create an
+ *   {@link AImageReader} object using the {@link AImageReader_new} method with one of the supported
+ *   output formats given by {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}. Then obtain a
+ *   ANativeWindow from it with {@link AImageReader_getWindow}.
+ *   If the AImageReader size is not set to a supported size, it will be rounded to a supported
+ *   size less than 1080p by the camera device.
+ *   </li>
+ *
+ * </ul>
+ *
+ * <p>The camera device will query each ANativeWindow's size and formats upon this
+ * call, so they must be set to a valid setting at this time.</p>
+ *
+ * <p>It can take several hundred milliseconds for the session's configuration to complete,
+ * since camera hardware may need to be powered on or reconfigured.</p>
+ *
+ * <p>If a prior ACameraCaptureSession already exists when this method is called, the previous
+ * session will no longer be able to accept new capture requests and will be closed. Any
+ * in-progress capture requests made on the prior session will be completed before it's closed.
+ * To minimize the transition time,
+ * the ACameraCaptureSession_abortCaptures method can be used to discard the remaining
+ * requests for the prior capture session before a new one is created. Note that once the new
+ * session is created, the old one can no longer have its captures aborted.</p>
+ *
+ * <p>Using larger resolution outputs, or more outputs, can result in slower
+ * output rate from the device.</p>
+ *
+ * <p>Configuring a session with an empty list will close the current session, if
+ * any. This can be used to release the current session's target surfaces for another use.</p>
+ *
+ * <p>While any of the sizes from {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS} can be used when
+ * a single output stream is configured, a given camera device may not be able to support all
+ * combination of sizes, formats, and targets when multiple outputs are configured at once.  The
+ * tables below list the maximum guaranteed resolutions for combinations of streams and targets,
+ * given the capabilities of the camera device.</p>
+ *
+ * <p>If an application tries to create a session using a set of targets that exceed the limits
+ * described in the below tables, one of three possibilities may occur. First, the session may
+ * be successfully created and work normally. Second, the session may be successfully created,
+ * but the camera device won't meet the frame rate guarantees as described in
+ * {@link ACAMERA_SCALER_AVAILABLE_MIN_FRAME_DURATIONS}. Or third, if the output set
+ * cannot be used at all, session creation will fail entirely, with
+ * {@link ACAMERA_ERROR_STREAM_CONFIGURE_FAIL} being returned.</p>
+ *
+ * <p>For the type column `PRIV` refers to output format {@link AIMAGE_FORMAT_PRIVATE},
+ * `YUV` refers to output format {@link AIMAGE_FORMAT_YUV_420_888},
+ * `JPEG` refers to output format {@link AIMAGE_FORMAT_JPEG},
+ * and `RAW` refers to output format {@link AIMAGE_FORMAT_RAW16}
+ *
+ *
+ * <p>For the maximum size column, `PREVIEW` refers to the best size match to the
+ * device's screen resolution, or to 1080p `(1920x1080)`, whichever is
+ * smaller. `RECORD` refers to the camera device's maximum supported recording resolution,
+ * as determined by <a href="http://developer.android.com/reference/android/media/CamcorderProfile.html">
+ * android.media.CamcorderProfiles</a>. And `MAXIMUM` refers to the
+ * camera device's maximum output resolution for that format or target from
+ * {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}.</p>
+ *
+ * <p>To use these tables, determine the number and the formats/targets of outputs needed, and
+ * find the row(s) of the table with those targets. The sizes indicate the maximum set of sizes
+ * that can be used; it is guaranteed that for those targets, the listed sizes and anything
+ * smaller from the list given by {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS} can be
+ * successfully used to create a session.  For example, if a row indicates that a 8 megapixel
+ * (MP) YUV_420_888 output can be used together with a 2 MP `PRIV` output, then a session
+ * can be created with targets `[8 MP YUV, 2 MP PRIV]` or targets `[2 MP YUV, 2 MP PRIV]`;
+ * but a session with targets `[8 MP YUV, 4 MP PRIV]`, targets `[4 MP YUV, 4 MP PRIV]`,
+ * or targets `[8 MP PRIV, 2 MP YUV]` would not be guaranteed to work, unless
+ * some other row of the table lists such a combination.</p>
+ *

+     * <p>When set to CANCEL, the camera device will cancel any active

+     * If a precapture metering sequence is already completed, and the camera
+     * device has implicitly locked the AE for subsequent still capture, the
+     * CANCEL trigger will unlock the AE and return to its initial AE state.</p>
+     * <p>The precapture sequence should be triggered before starting a
+     * high-quality still capture for final metering decisions to
+     * be made, and for firing pre-capture flash pulses to estimate
+     * scene brightness and required final capture flash power, when
+     * the flash is enabled.</p>
+     * <p>Normally, this entry should be set to START for only a
+     * single request, and the application should wait until the
+     * sequence completes before starting a new one.</p>
+     * <p>When a precapture metering sequence is finished, the camera device
+     * may lock the auto-exposure routine internally to be able to accurately expose the
+     * subsequent still capture image (<code>ACAMERA_CONTROL_CAPTURE_INTENT == STILL_CAPTURE</code>).
+     * For this case, the AE may not resume normal scan if no subsequent still capture is
+     * submitted. To ensure that the AE routine restarts normal scan, the application should
+     * submit a request with <code>ACAMERA_CONTROL_AE_LOCK == true</code>, followed by a request
+     * with <code>ACAMERA_CONTROL_AE_LOCK == false</code>, if the application decides not to submit a
+     * still capture request after the precapture sequence completes. Alternatively, for
+     * API level 23 or newer devices, the CANCEL can be used to unlock the camera device
+     * internally locked AE if the application doesn't submit a still capture request after
+     * the AE precapture trigger. Note that, the CANCEL was added in API level 23, and must not
+     * be used in devices that have earlier API levels.</p>
+     * <p>The exact effect of auto-exposure (AE) precapture trigger
+     * depends on the current AE mode and state; see

+     * <p>On LEGACY-level devices, the precapture trigger is not supported;
+     * capturing a high-resolution JPEG image will automatically trigger a

+     * potentially firing a pre-capture flash.</p>
+     * <p>Using the precapture trigger and the auto-focus trigger ACAMERA_CONTROL_AF_TRIGGER
+     * simultaneously is allowed. However, since these triggers often require cooperation between

+     * <p>A stall duration is how much extra time would get added
+     * to the normal minimum frame duration for a repeating request
+     * that has streams with non-zero stall.</p>
+     * <p>For example, consider JPEG captures which have the following
+     * characteristics:</p>
+     * <ul>
+     * <li>JPEG streams act like processed YUV streams in requests for which
+     * they are not included; in requests in which they are directly
+     * referenced, they act as JPEG streams. This is because supporting a
+     * JPEG stream requires the underlying YUV data to always be ready for
+     * use by a JPEG encoder, but the encoder will only be used (and impact
+     * frame duration) on requests that actually reference a JPEG stream.</li>
+     * <li>The JPEG processor can run concurrently to the rest of the camera
+     * pipeline, but cannot process more than 1 capture at a time.</li>
+     * </ul>
+     * <p>In other words, using a repeating YUV request would result
+     * in a steady frame rate (let's say it's 30 FPS). If a single
+     * JPEG request is submitted periodically, the frame rate will stay
+     * at 30 FPS (as long as we wait for the previous JPEG to return each
+     * time). If we try to submit a repeating YUV + JPEG request, then
+     * the frame rate will drop from 30 FPS.</p>
+     * <p>In general, submitting a new request with a non-0 stall time
+     * stream will <em>not</em> cause a frame rate drop unless there are still
+     * outstanding buffers for that stream from previous requests.</p>
+     * <p>Submitting a repeating request with streams (call this <code>S</code>)
+     * is the same as setting the minimum frame duration from
+     * the normal minimum frame duration corresponding to <code>S</code>, added with
+     * the maximum stall duration for <code>S</code>.</p>
+     * <p>If interleaving requests with and without a stall duration,
+     * a request will stall by the maximum of the remaining times
+     * for each can-stall stream with outstanding buffers.</p>
+     * <p>This means that a stalling request will not have an exposure start
+     * until the stall has completed.</p>
+     * <p>This should correspond to the stall duration when only that stream is
+     * active, with all processing (typically in android.*.mode) set to FAST
+     * or OFF. Setting any of the processing modes to HIGH_QUALITY
+     * effectively results in an indeterminate stall duration for all

+     * <p>The maximum frame rate that can be supported by a camera subsystem is

+     * <li>Availability of binning / skipping modes on the imager</li>
+     * <li>The bandwidth of the imager interface</li>
+     * <li>The bandwidth of the various ISP processing blocks</li>
+     * </ul>
+     * <p>Since these factors can vary greatly between different ISPs and
+     * sensors, the camera abstraction tries to represent the bandwidth
+     * restrictions with as simple a model as possible.</p>
+     * <p>The model presented has the following characteristics:</p>
+     * <ul>
+     * <li>The image sensor is always configured to output the smallest
+     * resolution possible given the application's requested output stream
+     * sizes.  The smallest resolution is defined as being at least as large
+     * as the largest requested output stream size; the camera pipeline must
+     * never digitally upsample sensor data when the crop region covers the
+     * whole sensor. In general, this means that if only small output stream
+     * resolutions are configured, the sensor can provide a higher frame
+     * rate.</li>
+     * <li>Since any request may use any or all the currently configured
+     * output streams, the sensor and ISP must be configured to support
+     * scaling a single capture to all the streams at the same time.  This
+     * means the camera pipeline must be ready to produce the largest
+     * requested output size without any delay.  Therefore, the overall
+     * frame rate of a given configured stream set is governed only by the
+     * largest requested stream resolution.</li>
+     * <li>Using more than one output stream in a request does not affect the
+     * frame duration.</li>
+     * <li>Certain format-streams may need to do additional background processing
+     * before data is consumed/produced by that stream. These processors
+     * can run concurrently to the rest of the camera pipeline, but
+     * cannot process more than 1 capture at a time.</li>
+     * </ul>
+     * <p>The necessary information for the application, given the model above,
+     * is provided via the android.scaler.streamConfigurationMap field using
+     * {@link android.hardware.camera2.params.StreamConfigurationMap#getOutputMinFrameDuration}.
+     * These are used to determine the maximum frame rate / minimum frame
+     * duration that is possible for a given stream configuration.</p>
+     * <p>Specifically, the application can use the following rules to
+     * determine the minimum frame duration it can request from the camera
+     * device:</p>
+     * <ol>
+     * <li>Let the set of currently configured input/output streams
+     * be called <code>S</code>.</li>
+     * <li>Find the minimum frame durations for each stream in <code>S</code>, by looking
+     * it up in android.scaler.streamConfigurationMap using {@link
+     * android.hardware.camera2.params.StreamConfigurationMap#getOutputMinFrameDuration}
+     * (with its respective size/format). Let this set of frame durations be
+     * called <code>F</code>.</li>
+     * <li>For any given request <code>R</code>, the minimum frame duration allowed
+     * for <code>R</code> is the maximum out of all values in <code>F</code>. Let the streams
+     * used in <code>R</code> be called <code>S_r</code>.</li>
+     * </ol>
+     * <p>If none of the streams in <code>S_r</code> have a stall time (listed in {@link
+     * android.hardware.camera2.params.StreamConfigurationMap#getOutputStallDuration}
+     * using its respective size/format), then the frame duration in <code>F</code>
+     * determines the steady state frame rate that the application will get
+     * if it uses <code>R</code> as a repeating request. Let this special kind of
+     * request be called <code>Rsimple</code>.</p>
+     * <p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved
+     * by a single capture of a new request <code>Rstall</code> (which has at least
+     * one in-use stream with a non-0 stall time) and if <code>Rstall</code> has the
+     * same minimum frame duration this will not cause a frame rate loss
+     * if all buffers from the previous <code>Rstall</code> have already been
+     * delivered.</p>

+     * <p>The shading map is for the entire active pixel array, and is not

+     * entry is the value of the shading compensation map over a specific

+     * map, and an active pixel array size (W x H), shading map entry
+     * (x,y) ϵ (0 ... N-1, 0 ... M-1) is the value of the shading map at
+     * pixel ( ((W-1)/(N-1)) * x, ((H-1)/(M-1)) * y) for the four color channels.
+     * The map is assumed to be bilinearly interpolated between the sample points.</p>

+     * channel for the even rows of a Bayer pattern, and Godd is the odd rows.

+namespace android {
+
+// Modulo class is used for intentionally wrapping variables such as
+// counters and timers.
+//
+// It may also be used for variables whose computation depends on the
+// associativity of addition or subtraction.
+//
+// Features:
+// 1) Modulo checks type sizes before performing operations to ensure
+//    that the wrap points match. This is critical for safe modular arithmetic.
+// 2) Modulo returns Modulo types from arithmetic operations, thereby
+//    avoiding unintentional use in a non-modular computation.  A Modulo
+//    type is converted to its base non-Modulo type through the value() function.
+// 3) Modulo separates out overflowable types from non-overflowable types.
+//    A signed overflow is technically undefined in C and C++.
+//    Modulo types do not participate in sanitization.
+// 4) Modulo comparisons are based on signed differences to account for wrap;
+//    this is not the same as the direct comparison of values.
+// 5) Safe use of binary arithmetic operations relies on conversions of
+//    signed operands to unsigned operands (which are modular arithmetic safe).
+//    Conversions which are implementation-defined are assumed to use 2's complement
+//    representation. (See A, B, C, D from the ISO/IEC FDIS 14882
+//    Information technology — Programming languages — C++).
+//
+// A: ISO/IEC 14882:2011(E) p84 section 4.7 Integral conversions
+// (2) If the destination type is unsigned, the resulting value is the least unsigned
+// integer congruent to the source integer (modulo 2^n where n is the number of bits
+// used to represent the unsigned type). [ Note: In a two’s complement representation,
+// this conversion is conceptual and there is no change in the bit pattern (if there
+// is no truncation). — end note ]
+// (3) If the destination type is signed, the value is unchanged if it can be represented
+// in the destination type (and bit-field width); otherwise, the value is
+// implementation-defined.
+//
+// B: ISO/IEC 14882:2011(E) p88 section 5 Expressions
+// (9) Many binary operators that expect operands of arithmetic or enumeration type
+// cause conversions and yield result types in a similar way. The purpose is to
+// yield a common type, which is also the type of the result. This pattern is called
+// the usual arithmetic conversions, which are defined as follows:
+// [...]
+// Otherwise, if both operands have signed integer types or both have unsigned
+// integer types, the operand with the type of lesser integer conversion rank shall be
+// converted to the type of the operand with greater rank.
+// — Otherwise, if the operand that has unsigned integer type has rank greater than
+// or equal to the rank of the type of the other operand, the operand with signed
+// integer type shall be converted to the type of the operand with unsigned integer type.
+//
+// C: ISO/IEC 14882:2011(E) p86 section 4.13 Integer conversion rank
+// [...] The rank of long long int shall be greater than the rank of long int,
+// which shall be greater than the rank of int, which shall be greater than the
+// rank of short int, which shall be greater than the rank of signed char.
+// — The rank of any unsigned integer type shall equal the rank of the corresponding
+// signed integer type.
+//
+// D: ISO/IEC 14882:2011(E) p75 section 3.9.1 Fundamental types
+// [...] Unsigned integers, declared unsigned, shall obey the laws of arithmetic modulo
+// 2^n where n is the number of bits in the value representation of that particular
+// size of integer.
+//
+// Note:
+// Other libraries do exist for safe integer operations which can detect the
+// possibility of overflow (SafeInt from MS and safe-iop in android).
+// Signed safe computation is also possible from the art header safe_math.h.

+A general purpose lookup utility that defines a mapping between X and Y as a
+continuous set of line segments with shared (x, y) end-points.
+The (x, y) points must be added in order, monotonically increasing in both x and y;
+a log warning is emitted if this does not happen (See general usage notes below).
+
+A limited history of (x, y) points is kept for space reasons (See general usage notes).
+
+In AudioFlinger, we use the LinearMap to associate track frames to
+sink frames.  When we want to obtain a client track timestamp, we first
+get a timestamp from the sink.  The sink timestamp's position (mPosition)
+corresponds to the sink frames written. We use LinearMap to figure out which track frame
+the sink frame corresponds to. This allows us to substitute a track frame for the
+the sink frame (keeping the mTime identical) and return that timestamp back to the client.
+
+The method findX() can be used to retrieve an x value from a given y value and is
+used for timestamps, similarly for findY() which is provided for completeness.
+
+We update the (track frame, sink frame) points in the LinearMap each time we write data
+to the sink by the AudioFlinger PlaybackThread (MixerThread).
+
+
+AudioFlinger Timestamp Notes:
+
+1) Example: Obtaining a track timestamp during playback.  In this case, the LinearMap
+looks something like this:
+
+Track Frame    Sink Frame
+(track start)
+0              50000  (track starts here, the sink may already be running)
+1000           51000
+2000           52000
+
+When we request a track timestamp, we call the sink getTimestamp() and get for example
+mPosition = 51020.  Using the LinearMap, we find we have played to track frame 1020.
+We substitute the sink mPosition of 51020 with the track position 1020,
+and return that timestamp to the app.
+
+2) Example: Obtaining a track timestamp duing pause. In this case, the LinearMap
+looks something like this:
+
+Track Frame    Sink Frame
+... (some time has gone by)
+15000          30000
+16000          31000
+17000          32000
+(pause here)
+(suppose we call sink getTimestamp() here and get sink mPosition = 31100; that means
+        we have played to track frame 16100.  The track timestamp mPosition will
+        continue to advance until the sink timestamp returns a value of mPosition
+        greater than 32000, corresponding to track frame 17000 when the pause was called).
+17000          33000
+17000          34000
+...
+
+3) If the track underruns, it appears as if a pause was called on that track.
+
+4) If there is an underrun in the HAL layer, then it may be possible that
+the sink getTimestamp() will return a value greater than the number of frames written
+(it should always be less). This should be rare, if not impossible by some
+HAL implementations of the sink getTimestamp. In that case, timing is lost
+and we will return the most recent track frame written.
+
+5) When called with no points in the map, findX() returns the start value (default 0).
+This is consistent with starting after a stop() or flush().
+
+6) Resuming after Track standby will be similar to coming out of pause, as the HAL ensures
+framesWritten() and getTimestamp() are contiguous for non-offloaded/direct tracks.
+
+7) LinearMap works for different speeds and sample rates as it uses
+linear interpolation. Since AudioFlinger only updates speed and sample rate
+exactly at the sample points pushed into the LinearMap, the returned values
+from findX() and findY() are accurate regardless of how many speed or sample
+rate changes are made, so long as the coordinate looked up is within the
+sample history.
+
+General usage notes:
+
+1) In order for the LinearMap to work reliably, you cannot look backwards more
+than the size of its circular buffer history, set upon creation (typically 16).
+If you look back further, the position is extrapolated either from a passed in
+extrapolation parameter or from the oldest line segment.
+
+2) Points must monotonically increase in x and y. The increment between adjacent
+points cannot be greater than signed 32 bits. Wrap in the x, y coordinates are supported,
+since we use differences in our computation.
+
+3) If the frame data is discontinuous (due to stop or flush) call reset() to clear
+the sample counter.
+
+4) If (x, y) are not strictly monotonic increasing, i.e. (x2 > x1) and (y2 > y1),
+then one or both of the inverses y = f(x) or x = g(y) may have multiple solutions.
+In that case, the most recent solution is returned by findX() or findY().  We
+do not warn if (x2 == x1) or (y2 == y1), but we do logcat warn if (x2 < x1) or
+(y2 < y1).
+
+5) Due to rounding it is possible x != findX(findY(x)) or y != findY(findX(y))
+even when the inverse exists. Nevertheless, the values should be close.

+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions

+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
