     * <span class="informal">Use it when you have all these Observables, but still nothing is happening.</span>
     *
     * `subscribe` is not a regular operator, but a method that calls Observable's internal `subscribe` function. It
     * might be for example a function that you passed to a {@link create} static factory, but most of the time it is
     * a library implementation, which defines what and when will be emitted by an Observable. This means that calling
     * `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often
     * thought.
     *
     * Apart from starting the execution of an Observable, this method allows you to listen for values
     * that an Observable emits, as well as for when it completes or errors. You can achieve this in two
     * following ways.
     *
     * The first way is creating an object that implements {@link Observer} interface. It should have methods
     * defined by that interface, but note that it should be just a regular JavaScript object, which you can create
     * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular do
     * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also
     * that your object does not have to implement all methods. If you find yourself creating a method that doesn't
     * do anything, you can simply omit it. Note however, that if `error` method is not provided, all errors will
     * be left uncaught.
     *
     * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.
     * This means you can provide three functions as arguments to `subscribe`, where first function is equivalent
     * of a `next` method, second of an `error` method and third of a `complete` method. Just as in case of Observer,
     * if you do not need to listen for something, you can omit a function, preferably by passing `undefined` or `null`,
     * since `subscribe` recognizes these functions by where they were placed in function call. When it comes
     * to `error` function, just as before, if not provided, errors emitted by an Observable will be thrown.
     *
     * Whatever style of calling `subscribe` you use, in both cases it returns a Subscription object.
     * This object allows you to call `unsubscribe` on it, which in turn will stop work that an Observable does and will clean
     * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback
     * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.
     *
     * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.
     * It is an Observable itself that decides when these functions will be called. For example {@link of}
     * by default emits all its values synchronously. Always check documentation for how given Observable
     * will behave when subscribed and if its default behavior can be modified with a {@link Scheduler}.
     *
     * @example <caption>Subscribe with an Observer</caption>
     * const sumObserver = {
     *   sum: 0,
     *   next(value) {
     *     console.log('Adding: ' + value);
     *     this.sum = this.sum + value;
     *   },
     *   error() { // We actually could just remove this method,
     *   },        // since we do not really care about errors right now.
     *   complete() {
     *     console.log('Sum equals: ' + this.sum);
     *   }
     * };
     *
     * Rx.Observable.of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.
     * .subscribe(sumObserver);
     *
     * // Logs:
     * // "Adding: 1"
     * // "Adding: 2"
     * // "Adding: 3"
     * // "Sum equals: 6"

     *
     * <span class="informal">Creates an Observable from DOM events, or Node.js
     * EventEmitter events or others.</span>
     *
     * <img src="./img/fromEvent.png" width="100%">
     *
     * `fromEvent` accepts as a first argument event target, which is an object with methods
     * for registering event handler functions. As a second argument it takes string that indicates
     * type of event we want to listen for. `fromEvent` supports selected types of event targets,
     * which are described in detail below. If your event target does not match any of the ones listed,
     * you should use {@link fromEventPattern}, which can be used on arbitrary APIs.
     * When it comes to APIs supported by `fromEvent`, their methods for adding and removing event
     * handler functions have different names, but they all accept a string describing event type
     * and function itself, which will be called whenever said event happens.
     *
     * Every time resulting Observable is subscribed, event handler function will be registered
     * to event target on given event type. When that event fires, value
     * passed as a first argument to registered function will be emitted by output Observable.
     * When Observable is unsubscribed, function will be unregistered from event target.
     *
     * Note that if event target calls registered function with more than one argument, second
     * and following arguments will not appear in resulting stream. In order to get access to them,
     * you can pass to `fromEvent` optional project function, which will be called with all arguments
     * passed to event handler. Output Observable will then emit value returned by project function,
     * instead of the usual value.
     *
     * Remember that event targets listed below are checked via duck typing. It means that
     * no matter what kind of object you have and no matter what environment you work in,
     * you can safely use `fromEvent` on that object if it exposes described methods (provided
     * of course they behave as was described above). So for example if Node.js library exposes
     * event target which has the same method names as DOM EventTarget, `fromEvent` is still
     * a good choice.
     *
     * If the API you use is more callback then event handler oriented (subscribed
     * callback function fires only once and thus there is no need to manually
     * unregister it), you should use {@link bindCallback} or {@link bindNodeCallback}
     * instead.
     *
     * `fromEvent` supports following types of event targets:
     *
     * **DOM EventTarget**
     *
     * This is an object with `addEventListener` and `removeEventListener` methods.
     *
     * In the browser, `addEventListener` accepts - apart from event type string and event
     * handler function arguments - optional third parameter, which is either an object or boolean,
     * both used for additional configuration how and when passed function will be called. When
     * `fromEvent` is used with event target of that type, you can provide this values
     * as third parameter as well.
     *
     * **Node.js EventEmitter**
     *
     * An object with `addListener` and `removeListener` methods.
     *
     * **JQuery-style event target**
     *
     * An object with `on` and `off` methods
     *
     * **DOM NodeList**
     *
     * List of DOM Nodes, returned for example by `document.querySelectorAll` or `Node.childNodes`.
     *
     * Although this collection is not event target in itself, `fromEvent` will iterate over all Nodes
     * it contains and install event handler function in every of them. When returned Observable
     * is unsubscribed, function will be removed from all Nodes.
     *
     * **DOM HtmlCollection**
     *
     * Just as in case of NodeList it is a collection of DOM nodes. Here as well event handler function is
     * installed and removed in each of elements.
     *
     *
     * @example <caption>Emits clicks happening on the DOM document</caption>
     * var clicks = Rx.Observable.fromEvent(document, 'click');
     * clicks.subscribe(x => console.log(x));
     *
     * // Results in:
     * // MouseEvent object logged to console every time a click
     * // occurs on the document.
     *
     *
     * @example <caption>Use addEventListener with capture option</caption>
     * var clicksInDocument = Rx.Observable.fromEvent(document, 'click', true); // note optional configuration parameter
     *                                                                          // which will be passed to addEventListener
     * var clicksInDiv = Rx.Observable.fromEvent(someDivInDocument, 'click');
     *
     * clicksInDocument.subscribe(() => console.log('document'));
     * clicksInDiv.subscribe(() => console.log('div'));
     *
     * // By default events bubble UP in DOM tree, so normally
     * // when we would click on div in document
     * // "div" would be logged first and then "document".
     * // Since we specified optional `capture` option, document
     * // will catch event when it goes DOWN DOM tree, so console
     * // will log "document" and then "div".

 * Combines multiple Observables to create an Observable whose values are

 * computes a formula using the latest values from all the inputs, then emits
 * the output of that formula.</span>
 *
 * <img src="./img/combineLatest.png" width="100%">
 *
 * `combineLatest` combines the values from all the Observables passed as
 * arguments. This is done by subscribing to each Observable in order and,
 * whenever any Observable emits, collecting an array of the most recent
 * values from each Observable. So if you pass `n` Observables to operator,
 * returned Observable will always emit an array of `n` values, in order
 * corresponding to order of passed Observables (value from the first Observable
 * on the first place and so on).
 *
 * Static version of `combineLatest` accepts either an array of Observables
 * or each Observable can be put directly as an argument. Note that array of
 * Observables is good choice, if you don't know beforehand how many Observables
 * you will combine. Passing empty array will result in Observable that
 * completes immediately.
 *
 * To ensure output array has always the same length, `combineLatest` will
 * actually wait for all input Observables to emit at least once,
 * before it starts emitting results. This means if some Observable emits
 * values before other Observables started emitting, all that values but last
 * will be lost. On the other hand, is some Observable does not emit value but
 * completes, resulting Observable will complete at the same moment without
 * emitting anything, since it will be now impossible to include value from
 * completed Observable in resulting array. Also, if some input Observable does
 * not emit any value and never completes, `combineLatest` will also never emit
 * and never complete, since, again, it will wait for all streams to emit some
 * value.
 *
 * If at least one Observable was passed to `combineLatest` and all passed Observables
 * emitted something, resulting Observable will complete when all combined
 * streams complete. So even if some Observable completes, result of
 * `combineLatest` will still emit values when other Observables do. In case
 * of completed Observable, its value from now on will always be the last
 * emitted value. On the other hand, if any Observable errors, `combineLatest`
 * will error immediately as well, and all other Observables will be unsubscribed.
 *
 * `combineLatest` accepts as optional parameter `project` function, which takes
 * as arguments all values that would normally be emitted by resulting Observable.
 * `project` can return any kind of value, which will be then emitted by Observable
 * instead of default array. Note that `project` does not take as argument that array
 * of values, but values themselves. That means default `project` can be imagined
 * as function that takes all its arguments and puts them into an array.
 *
 *
 * @example <caption>Combine two timer Observables</caption>
 * const firstTimer = Rx.Observable.timer(0, 1000); // emit 0, 1, 2... after every second, starting from now
 * const secondTimer = Rx.Observable.timer(500, 1000); // emit 0, 1, 2... after every second, starting 0,5s from now
 * const combinedTimers = Rx.Observable.combineLatest(firstTimer, secondTimer);

 *
 * <img src="./img/concat.png" width="100%">
 *
 * `concat` joins multiple Observables together, by subscribing to them one at a time and
 * merging their results into the output Observable. You can pass either an array of
 * Observables, or put them directly as arguments. Passing an empty array will result
 * in Observable that completes immediately.
 *
 * `concat` will subscribe to first input Observable and emit all its values, without
 * changing or affecting them in any way. When that Observable completes, it will
 * subscribe to then next Observable passed and, again, emit its values. This will be
 * repeated, until the operator runs out of Observables. When last input Observable completes,
 * `concat` will complete as well. At any given moment only one Observable passed to operator
 * emits values. If you would like to emit values from passed Observables concurrently, check out
 * {@link merge} instead, especially with optional `concurrent` parameter. As a matter of fact,
 * `concat` is an equivalent of `merge` operator with `concurrent` parameter set to `1`.
 *
 * Note that if some input Observable never completes, `concat` will also never complete
 * and Observables following the one that did not complete will never be subscribed. On the other
 * hand, if some Observable simply completes immediately after it is subscribed, it will be
 * invisible for `concat`, which will just move on to the next Observable.
 *
 * If any Observable in chain errors, instead of passing control to the next Observable,
 * `concat` will error immediately as well. Observables that would be subscribed after
 * the one that emitted error, never will.
 *
 * If you pass to `concat` the same Observable many times, its stream of values
 * will be "replayed" on every subscription, which means you can repeat given Observable
 * as many times as you like. If passing the same Observable to `concat` 1000 times becomes tedious,
 * you can always use {@link repeat}.
 *
 * @example <caption>Concatenate a timer counting from 0 to 3 with a synchronous sequence from 1 to 10</caption>
 * var timer = Rx.Observable.interval(1000).take(4);
 * var sequence = Rx.Observable.range(1, 10);

 * var timer1 = Rx.Observable.interval(1000).take(10);
 * var timer2 = Rx.Observable.interval(2000).take(6);
 * var timer3 = Rx.Observable.interval(500).take(10);
 * var result = Rx.Observable.concat([timer1, timer2, timer3]); // note that array is passed
 * result.subscribe(x => console.log(x));
 *
 * // results in the following:
 * // (Prints to console sequentially)
 * // -1000ms-> 0 -1000ms-> 1 -1000ms-> ... 9
 * // -2000ms-> 0 -2000ms-> 1 -2000ms-> ... 5

 *
 * <img src="./img/timeout.png" width="100%">
 *
 * `timeout` operator accepts as an argument either a number or a Date.
 *
 * If number was provided, it returns an Observable that behaves like a source
 * Observable, unless there is a period of time where there is no value emitted.
 * So if you provide `100` as argument and first value comes after 50ms from
 * the moment of subscription, this value will be simply re-emitted by the resulting
 * Observable. If however after that 100ms passes without a second value being emitted,
 * stream will end with an error and source Observable will be unsubscribed.
 * These checks are performed throughout whole lifecycle of Observable - from the moment
 * it was subscribed to, until it completes or errors itself. Thus every value must be
 * emitted within specified period since previous value.
 *
 * If provided argument was Date, returned Observable behaves differently. It throws
 * if Observable did not complete before provided Date. This means that periods between
 * emission of particular values do not matter in this case. If Observable did not complete
 * before provided Date, source Observable will be unsubscribed. Other than that, resulting
 * stream behaves just as source Observable.
 *
 * `timeout` accepts also a Scheduler as a second parameter. It is used to schedule moment (or moments)
 * when returned Observable will check if source stream emitted value or completed.
 *
 * @example <caption>Check if ticks are emitted within certain timespan</caption>
 * const seconds = Rx.Observable.interval(1000);
 *
 * seconds.timeout(1100) // Let's use bigger timespan to be safe,
 *                       // since `interval` might fire a bit later then scheduled.
 * .subscribe(
 *     value => console.log(value), // Will emit numbers just as regular `interval` would.
 *     err => console.log(err) // Will never be called.
 * );
 *
 * seconds.timeout(900).subscribe(
 *     value => console.log(value), // Will never be called.
 *     err => console.log(err) // Will emit error before even first value is emitted,
 *                             // since it did not arrive within 900ms period.
 * );
 *
 * @example <caption>Use Date to check if Observable completed</caption>
 * const seconds = Rx.Observable.interval(1000);
 *
 * seconds.timeout(new Date("December 17, 2020 03:24:00"))
 * .subscribe(
 *     value => console.log(value), // Will emit values as regular `interval` would
 *                                  // until December 17, 2020 at 03:24:00.
 *     err => console.log(err) // On December 17, 2020 at 03:24:00 it will emit an error,

/**
 * Returns an Observable that emits all items emitted by the source Observable that are distinct by comparison from previous items.
 *
 * If a keySelector function is provided, then it will project each value from the source observable into a new value that it will
 * check for equality with previously projected values. If a keySelector function is not provided, it will use each value from the
 * source observable directly with an equality check against previous values.
 *
 * In JavaScript runtimes that support `Set`, this operator will use a `Set` to improve performance of the distinct value checking.
 *
 * In other runtimes, this operator will use a minimal implementation of `Set` that relies on an `Array` and `indexOf` under the
 * hood, so performance will degrade as more values are checked for distinction. Even in newer browsers, a long-running `distinct`
 * use might result in memory leaks. To help alleviate this in some scenarios, an optional `flushes` parameter is also provided so
 * that the internal `Set` can be "flushed", basically clearing it of values.
 *
 * @example <caption>A simple example with numbers</caption>
 * Observable.of(1, 1, 2, 2, 2, 1, 2, 3, 4, 3, 2, 1)
 *   .distinct()
 *   .subscribe(x => console.log(x)); // 1, 2, 3, 4
 *

 *    name: string

/**
 *
 * Re-emits all notifications from source Observable with specified scheduler.
 *
 * <span class="informal">Ensure a specific scheduler is used, from outside of an Observable.</span>
 *
 * `observeOn` is an operator that accepts a scheduler as a first parameter, which will be used to reschedule
 * notifications emitted by the source Observable. It might be useful, if you do not have control over
 * internal scheduler of a given Observable, but want to control when its values are emitted nevertheless.
 *
 * Returned Observable emits the same notifications (nexted values, complete and error events) as the source Observable,
 * but rescheduled with provided scheduler. Note that this doesn't mean that source Observables internal
 * scheduler will be replaced in any way. Original scheduler still will be used, but when the source Observable emits
 * notification, it will be immediately scheduled again - this time with scheduler passed to `observeOn`.
 * An anti-pattern would be calling `observeOn` on Observable that emits lots of values synchronously, to split
 * that emissions into asynchronous chunks. For this to happen, scheduler would have to be passed into the source
 * Observable directly (usually into the operator that creates it). `observeOn` simply delays notifications a
 * little bit more, to ensure that they are emitted at expected moments.
 *
 * As a matter of fact, `observeOn` accepts second parameter, which specifies in milliseconds with what delay notifications
 * will be emitted. The main difference between {@link delay} operator and `observeOn` is that `observeOn`
 * will delay all notifications - including error notifications - while `delay` will pass through error
 * from source Observable immediately when it is emitted. In general it is highly recommended to use `delay` operator
 * for any kind of delaying of values in the stream, while using `observeOn` to specify which scheduler should be used
 * for notification emissions in general.
 *
 * @example <caption>Ensure values in subscribe are called just before browser repaint.</caption>
 * const intervals = Rx.Observable.interval(10); // Intervals are scheduled
 *                                               // with async scheduler by default...
 *
 * intervals
 * .observeOn(Rx.Scheduler.animationFrame)       // ...but we will observe on animationFrame
 * .subscribe(val => {                           // scheduler to ensure smooth animation.
 *   someDiv.style.height = val + 'px';
 * });
 *
 * @see {@link delay}
 *
 * @param {IScheduler} scheduler Scheduler that will be used to reschedule notifications from source Observable.
 * @param {number} [delay] Number of milliseconds that states with what delay every notification should be rescheduled.
 * @return {Observable<T>} Observable that emits the same notifications as the source Observable,

 *
 * Errors if Observable does not emit a value in given time span.
 *
 * <span class="informal">Timeouts on Observable that doesn't emit values fast enough.</span>
 *
 * <img src="./img/timeout.png" width="100%">
 *
 * `timeout` operator accepts as an argument either a number or a Date.
 *
 * If number was provided, it returns an Observable that behaves like a source
 * Observable, unless there is a period of time where there is no value emitted.
 * So if you provide `100` as argument and first value comes after 50ms from
 * the moment of subscription, this value will be simply re-emitted by the resulting
 * Observable. If however after that 100ms passes without a second value being emitted,
 * stream will end with an error and source Observable will be unsubscribed.
 * These checks are performed throughout whole lifecycle of Observable - from the moment
 * it was subscribed to, until it completes or errors itself. Thus every value must be
 * emitted within specified period since previous value.
 *
 * If provided argument was Date, returned Observable behaves differently. It throws
 * if Observable did not complete before provided Date. This means that periods between
 * emission of particular values do not matter in this case. If Observable did not complete
 * before provided Date, source Observable will be unsubscribed. Other than that, resulting
 * stream behaves just as source Observable.
 *
 * `timeout` accepts also a Scheduler as a second parameter. It is used to schedule moment (or moments)
 * when returned Observable will check if source stream emitted value or completed.
 *
 * @example <caption>Check if ticks are emitted within certain timespan</caption>
 * const seconds = Rx.Observable.interval(1000);
 *
 * seconds.timeout(1100) // Let's use bigger timespan to be safe,
 *                       // since `interval` might fire a bit later then scheduled.
 * .subscribe(
 *     value => console.log(value), // Will emit numbers just as regular `interval` would.
 *     err => console.log(err) // Will never be called.
 * );
 *
 * seconds.timeout(900).subscribe(
 *     value => console.log(value), // Will never be called.
 *     err => console.log(err) // Will emit error before even first value is emitted,
 *                             // since it did not arrive within 900ms period.
 * );
 *
 * @example <caption>Use Date to check if Observable completed</caption>
 * const seconds = Rx.Observable.interval(1000);
 *
 * seconds.timeout(new Date("December 17, 2020 03:24:00"))
 * .subscribe(
 *     value => console.log(value), // Will emit values as regular `interval` would
 *                                  // until December 17, 2020 at 03:24:00.
 *     err => console.log(err) // On December 17, 2020 at 03:24:00 it will emit an error,
 *                             // since Observable did not complete by then.
 * );

 * in intervals.
 *
 * If you just want to "defer" task, that is to perform it right after currently

 * Rx.Scheduler.queue.schedule(() => {
 *   Rx.Scheduler.queue.schedule(() => console.log('second')); // will not happen now, but will be put on a queue

 *   console.log('first');

/**
 * @class MarkerComponent
 *
 * @classdesc Component for showing and editing 3D marker objects.
 *
 * The `add` method is used for adding new markers or replacing
 * markers already in the set.
 *
 * If a marker already in the set has the same
 * id as one of the markers added, the old marker will be removed and
 * the added marker will take its place.
 *
 * It is not possible to update markers in the set by updating any properties
 * directly on the marker object. Markers need to be replaced by
 * re-adding them for updates to geographic position or configuration
 * to be reflected.
 *
 * Markers added to the marker component can be either interactive
 * or non-interactive. Different marker types define their behavior.
 * Markers with interaction support can be configured with options
 * to respond to dragging inside the viewer and be detected when
 * retrieving markers from pixel points with the `getMarkerIdAt` method.
 *
 * To retrive and use the marker component
 *
 * @example
 * ```
 * var viewer = new Mapillary.Viewer(
 *     "<element-id>",
 *     "<client-id>",
 *     "<my key>",
 *     { component: { marker: true } });
 *
 * var markerComponent = viewer.getComponent("marker");
 * ```

/**
 * @class TagComponent
 *
 * @classdesc Component for showing and editing tags with different
 * geometries composed from 2D basic image coordinates (see the
 * {@link Viewer} class documentation for more information about coordinate
 * systems).
 *
 * The `add` method is used for adding new tags or replacing
 * tags already in the set. Tags are removed by id.
 *
 * If a tag already in the set has the same
 * id as one of the tags added, the old tag will be removed and
 * the added tag will take its place.
 *
 * The tag component mode can be set to either be non interactive or
 * to be in creating mode of a certain geometry type.
 *
 * The tag properties can be updated at any time and the change will
 * be visibile immediately.
 *
 * Tags are only relevant to a single image because they are based on
 * 2D basic image coordinates. Tags related to a certain image should
 * be removed when the viewer is moved to another node.
 *
 * To retrive and use the tag component
 *
 * @example
 * ```
 * var viewer = new Mapillary.Viewer(
 *     "<element-id>",
 *     "<client-id>",
 *     "<my key>",
 *     { component: { tag: true } });
 *
 * var tagComponent = viewer.getComponent("tag");
 * ```

 * e = Math.sqrt((a^2 - b^2) / a^2)
 * e' = Math.sqrt((a^2 - b^2) / b^2)

 * h = height above ellipsoid (altitude)
 * N = Radius of curvature (meters)
 *   = a / Math.sqrt(1 - e^2 * sin(phi)^2)

 *
 * phi = arctan((Z + e'^2 * b * sin(theta)^3) / (p - e^2 * a * cos(theta)^3))
 * lambda = arctan(Y / X)
 * h = p / cos(phi) - N
 *
 * where
 *
 * p = Math.sqrt(X^2 + Y^2)
 * theta = arctan(Z * a / p * b)
 *
 * In the ENU reference frame the x-axis points to the
 * East, the y-axis to the North and the z-axis Up. All values
 * in meters.
 *
 * The ECEF to ENU conversion is performed using the following:
 *
 * | x |   |       -sin(lambda_r)                cos(lambda_r)             0      | | X - X_r |

 *
 * where
 *
 * phi_r = latitude of reference
 * lambda_r = longitude of reference
 * X_r, Y_r, Z_r = ECEF coordinates of reference

/**
 * @class Node
 *
 * @classdesc Represents a node in the navigation graph.
 *
 * Explanation of position and bearing properties:
 *
 * When images are uploaded they will have GPS information in the EXIF, this is what
 * is called `originalLatLon`(@link Node#originalLatLon).
 *
 * When Structure from Motions has been run for a node a `computedLatLon` that
 * differs from the `originalLatLon` will be created. It is different because
 * GPS positions are not very exact and SfM aligns the camera positions according
 * to the 3D reconstruction (@link Node#computedLatLon).
 *
 * At last there exist a `latLon` property which evaluates to
 * the `computedLatLon` from SfM if it exists but falls back
 * to the `originalLatLon` from the EXIF GPS otherwise (@link Node#latlon).
 *
 * Everything that is done in in the Viewer is based on the SfM positions,
 * i.e. `computedLatLon`. That is why the smooth transitions go in the right
 * direction (nd not in strange directions because of bad GPS).
 *
 * E.g. when placing a marker in the Viewer it is relative to the SfM
 * position i.e. the `computedLatLon`.
 *
 * The same concept as above also applies to the compass angle (or bearing) properties
 * `originalCa`, `computedCa` and `ca`.

 * @class Viewer
 *
 * @classdesc The Viewer object represents the navigable image viewer.
 * Create a Viewer by specifying a container, client ID, image key and
 * other options. The viewer exposes methods and events for programmatic
 * interaction.
 *
 * The viewer works with a few different coordinate systems.
 *
 * Container pixel coordinates
 *
 * Pixel coordinates are coordinates on the viewer container. The origin is
 * in the top left corner of the container. The axes are
 * directed according to the following for a viewer container with a width
 * of 640 pixels and height of 480 pixels.
 *
 * ```
 * (0,0)                          (640, 0)
 *      +------------------------>
 *      |
 *      |
 *      |
 *      v                        +
 * (0, 480)                       (640, 480)
 * ```
 *
 * Basic image coordinates
 *
 * Basic image coordinates represents points in the original image adjusted for
 * orientation. They range from 0 to 1 on both axes. The origin is in the top left
 * corner of the image and the axes are directed
 * according to the following for all image types.
 *
 * ```
 * (0,0)                          (1, 0)
 *      +------------------------>
 *      |
 *      |
 *      |
 *      v                        +
 * (0, 1)                         (1, 1)
 * ```
 *
 * For every camera viewing direction it is possible to convert between these
 * two coordinate systems for the current node. The image can be panned and
 * zoomed independently of the size of the viewer container resulting in
 * different conversion results for different viewing directions.

    /**
     * Create a new viewer instance.
     *
     * @description It is possible to initialize the viewer with or
     * without a key.
     *
     * When initializing with a key the viewer is bound to that key
     * until the node/image for that key has been successfully loaded.
     * Also, a cover with the image of the key will be shown.
     * If the data for that key can not be loaded because the key is
     * faulty or other errors occur it is not possible to navigate
     * to another key because the viewer is not navigable. The viewer
     * becomes navigable when the data for the has been loaded and
     * the image is shown in the viewer. This wayof initializing
     * the viewer is mostly for embedding in blog posts and similar
     * where one wants to show a specific image initially.
     *
     * If the viewer is initialized without a key (with null or
     * undefined) it is not bound to any particular key and it is
     * possible to move to any key with `viewer.moveToKey("<my-image-key>")`.
     * If the first move to a key fails it is possible to move to another
     * key. The viewer will show a black background until a move
     * succeeds. This way of intitializing is suited for a map-viewer
     * application when the initial key is not known at implementation
     * time.
     *
     * @param {string} id - Required `id` of a DOM element which will
     * be transformed into the viewer.
     * @param {string} clientId - Required `Mapillary API ClientID`. Can
     * be obtained from https://www.mapillary.com/app/settings/developers.
     * @param {string} key - Optional `image-key` to start from. The key
     * can be any Mapillary image. If a key is provided the viewer is
     * bound to that key until it has been fully loaded. If null is provided
     * no image is loaded at viewer initialization and the viewer is not
     * bound to any particular key. Any image can then be navigated to
     * with e.g. `viewer.moveToKey("<my-image-key>")`.
     * @param {IViewerOptions} options - Optional configuration object
     * specifing Viewer's and the components' initial setup.
     * @param {string} token - Optional bearer token for API requests of
     * protected resources.
     *
