 * inflate(data[, options]) -> Uint8Array|Array|String

 *
 * Decompress `data` with inflate/ungzip and `options`. Autodetect
 * format via wrapper header by default. That's why we don't provide
 * separate `ungzip` method.
 *
 * Supported options are:
 *
 * - windowBits
 *
 * [http://zlib.net/manual.html#Advanced](http://zlib.net/manual.html#Advanced)
 * for more information.
 *
 * Sugar (options):
 *
 * - `raw` (Boolean) - say that we work with raw stream, if you don't wish to specify
 *   negative windowBits implicitly.
 * - `to` (String) - if equal to 'string', then result will be converted
 *   from utf8 to utf16 (javascript) string. When string output requested,
 *   chunk length can differ from `chunkSize`, depending on content.
 *
 *
 * ##### Example:
 *
 * ```javascript
 * var pako = require('pako')
 *   , input = pako.deflate([1,2,3,4,5,6,7,8,9])
 *   , output;
 *
 * try {

/*
   Decode literal, length, and distance codes and write out the resulting
   literal and match bytes until either not enough input or output is
   available, an end-of-block is encountered, or a data error is encountered.
   When large enough input and output buffers are supplied to inflate(), for
   example, a 16K input buffer and a 64K output buffer, more than 95% of the
   inflate execution time is spent in this routine.

   Entry assumptions:

        state.mode === LEN
        strm.avail_in >= 6
        strm.avail_out >= 258
        start >= strm.avail_out
        state.bits < 8

   On return, state.mode is one of:

        LEN -- ran out of enough output space or enough available input
        TYPE -- reached end of block code, inflate() to interpret next block
        BAD -- error in block data

   Notes:

    - The maximum input bits used by a length/distance pair is 15 bits for the
      length code, 5 bits for the length extra, 15 bits for the distance code,
      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
      Therefore if strm.avail_in >= 6, then there is enough input to avoid
      checking for available input while decoding.

    - The maximum bytes that a single length/distance pair can output is 258
      bytes, which is the maximum length that can be coded.  inflate_fast()
      requires strm.avail_out >= 258 for each loop to avoid checking for
      output space.

 when a window is already in use, or when output has been written during this

 It is also called to create a window for dictionary data when a dictionary

 Providing output buffers larger than 32K to inflate() should provide a speed
 advantage, since only the last 32K of output is copied to the sliding window
 upon return from inflate(), and since all distances after the first 32K of
 output will fall in the output data, making match copies simpler and faster.
 The advantage may be dependent on the size of the processor's data caches.

   Process a set of code lengths to create a canonical Huffman code.  The
   code lengths are lens[0..codes-1].  Each length corresponds to the
   symbols 0..codes-1.  The Huffman code is generated by first sorting the
   symbols by length from short to long, and retaining the symbol order
   for codes with equal lengths.  Then the code starts with all zero bits
   for the first code of the shortest length, and the codes are integer
   increments for the same length, and zeros are appended as the length
   increases.  For the deflate format, these bits are stored backwards
   from their more natural integer increment ordering, and so when the
   decoding tables are built in the large loop below, the integer codes
   are incremented backwards.

   This routine assumes, but does not check, that all of the entries in
   lens[] are in the range 0..MAXBITS.  The caller must assure this.
   1..MAXBITS is interpreted as that code length.  zero means that that
   symbol does not occur in this code.

   The codes are sorted by computing a count of codes for each length,
   creating from that a table of starting indices for each length in the
   sorted table, and then entering the symbols in order in the sorted
   table.  The sorted table is work[], with that space being provided by
   the caller.

   The length counts are used for other purposes as well, i.e. finding
   the minimum and maximum length codes, determining if there are any
   codes at all, checking for a valid set of lengths, and looking ahead
   at length counts to determine sub-table sizes when building the
   decoding tables.

   Create and fill in decoding tables.  In this loop, the table being
   filled is at next and has curr index bits.  The code being used is huff
   with length len.  That code is converted to an index by dropping drop
   bits off of the bottom.  For codes where len is less than drop + curr,
   those top drop + curr - len bits are incremented through all values to
   fill the table with replicated entries.

   root is the number of index bits for the root table.  When len exceeds
   root, sub-tables are created pointed to by the root entry with an index
   of the low root bits of huff.  This is saved in low to check for when a
   new sub-table should be started.  drop is zero when the root table is
   being filled, and drop is root when sub-tables are being filled.

   When a new sub-table is needed, it is necessary to look ahead in the
   code lengths to determine what size sub-table is needed.  The length
   counts are used for this, and so count[] is decremented as codes are
   entered in the tables.

   used keeps track of how many table entries have been allocated from the
   provided *table space.  It is checked for LENS and DIST tables against
   the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in
   the initial root table size constants.  See the comments in inftrees.h
   for more information.

   sym increments through all symbols, and the loop terminates when
   all codes of length max, i.e. all codes, have been processed.  This
   routine permits incomplete codes, so another loop after this one fills
   in the rest of the decoding tables with invalid code markers.

/**
 * @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 Popup
 *
 * @classdesc Popup instance for rendering custom HTML content
 * on top of images. Popups are based on 2D basic image coordinates
 * (see the {@link Viewer} class documentation for more information about coordinate
 * systems) and a certain popup is therefore only relevant to a single image.
 * Popups related to a certain image should be removed when moving
 * to another image.
 *
 * A popup must have both its content and its point or rect set to be
 * rendered. Popup options can not be updated after creation but the
 * basic point or rect as well as its content can be changed by calling
 * the appropriate methods.
 *
 * To create and add one `Popup` with default configuration
 * (tooltip visuals and automatic float) and one with specific options
 * use
 *
 * @example
 * ```
 * var defaultSpan = document.createElement('span');
 * defaultSpan.innerHTML = 'hello default';
 *
 * var defaultPopup = new Mapillary.PopupComponent.Popup();
 * defaultPopup.setDOMContent(defaultSpan);
 * defaultPopup.setBasicPoint([0.3, 0.3]);
 *
 * var cleanSpan = document.createElement('span');
 * cleanSpan.innerHTML = 'hello clean';
 *
 * var cleanPopup = new Mapillary.PopupComponent.Popup({
 *     clean: true,
 *     float: Mapillary.Alignment.Top,
 *     offset: 10,
 *     opacity: 0.7,
 * });
 *
 * cleanPopup.setDOMContent(cleanSpan);
 * cleanPopup.setBasicPoint([0.6, 0.6]);
 *
 * popupComponent.add([defaultPopup, cleanPopup]);
 * ```

/**
 * @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");
 * ```

/**
 * @class GeoCoords
 *
 * @classdesc Converts coordinates between the geodetic (WGS84),
 * Earth-Centered, Earth-Fixed (ECEF) and local topocentric
 * East, North, Up (ENU) reference frames.
 *
 * The WGS84 has latitude (degrees), longitude (degrees) and
 * altitude (meters) values.
 *
 * The ECEF Z-axis pierces the north pole and the
 * XY-axis defines the equatorial plane. The X-axis extends
 * from the geocenter to the intersection of the Equator and
 * the Greenwich Meridian. All values in meters.
 *
 * The WGS84 parameters are:
 *
 * a = 6378137
 * b = a * (1 - f)
 * f = 1 / 298.257223563
 * e = Math.sqrt((a^2 - b^2) / a^2)
 * e' = Math.sqrt((a^2 - b^2) / b^2)
 *
 * The WGS84 to ECEF conversion is performed using the following:
 *
 * X = (N - h) * cos(phi) * cos(lambda)
 * Y = (N + h) * cos(phi) * sin(lambda)
 * Z = (b^2 * N / a^2 + h) * sin(phi)
 *
 * where
 *
 * phi = latitude
 * lambda = longitude
 * h = height above ellipsoid (altitude)
 * N = Radius of curvature (meters)
 *   = a / Math.sqrt(1 - e^2 * sin(phi)^2)
 *
 * The ECEF to WGS84 conversion is performed using the following:
 *
 * 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 |
 * | y | = | -sin(phi_r) * cos(lambda_r)  -sin(phi_r) * sin(lambda_r)  cos(phi_r) | | Y - Y_r |
 * | z |   |  cos(phi_r) * cos(lambda_r)   cos(phi_r) * sin(lambda_r)  sin(phi_r) | | Z - Z_r |
 *
 * where
 *
 * phi_r = latitude of reference
 * lambda_r = longitude of reference
 * X_r, Y_r, Z_r = ECEF coordinates of reference
 *
 * The ENU to ECEF conversion is performed by solving the above equation for X, Y, Z.
 *
 * WGS84 to ENU and ENU to WGS84 are two step conversions with ECEF calculated in
 * the first step for both conversions.

/**
 * @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.
 *
 * In the case of asynchronous methods, MapillaryJS returns promises to
 * the results. Notifications are always emitted through JavaScript events.
 *
 * 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 you want to show a specific image in the viewer from
     * the start you should initialize it with a key.
     *
     * When you do not know the first image key at implementation
     * time, e.g. in a map-viewer application you should initialize
     * the viewer without a key and call `moveToKey` instead.
     *
     * When initializing with a key the viewer is bound to that key
     * until the node 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 key has been loaded and
     * the image is shown in the viewer. This way of 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 | HTMLElement} container - The HTML element in which
     * MapillaryJS will render the viewer, or the element's string `id`. The
     * specified element must have no children.
     * @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.
     *
     * @example
     * ```
     * var viewer = new Mapillary.Viewer("<element-id>", "<client-id>", "<image-key>");

     * simple {@link Node} property. A value must be a string, number, or
     * boolean. Strictly-typed comparisons are used. The values
     * `f0, ..., fn` of the combining filter must be filter expressions.
     *
     * Clear the filter by setting it to null or empty array.
     *
     * Commonly used filter properties (see the {@link Node} class
     * documentation for a full list of properties that can be used
     * in a filter) and common use cases:
     *
     * ```
     * fullPano        // Show only full 360 panoramas or not
     * organizationKey // Show images from one or several organizations
     * sequenceKey     // Show images from one or several sequences
     * userKey         // Show images from one or several users
     * capturedAt      // Show images from a certain time interval
     * ```
     *
     * @param {FilterExpression} filter - The filter expression.
     * @returns {Promise<void>} Promise that resolves after filter is applied.
     *
     * @example
     * ```
     * viewer.setFilter(["==", "sequenceKey", "<my sequence key>"]);
     *
     * // Other examples
     * // viewer.setFilter(["==", "organizationKey", "<my organization key>"]);
     * // viewer.setFilter(["in", "userKey", "<my user key #1>", "<my user key #2>"]);
