/**
 * @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
 * ```

 * 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.

 * 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`.

/**
 * @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

     * 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.
