/**
 * Abstracts click & drag interactions
 *
 * During the interaction, a "coverSlip" element - a transparent
 * div covering the whole page - is created, which has two key effects:
 * - Lets you drag beyond the boundaries of the plot itself without
 *   dropping (but if you drag all the way out of the browser window the
 *   interaction will end)
 * - Freezes the cursor: whatever mouse cursor the drag element had when the
 *   interaction started gets copied to the coverSlip for use until mouseup
 *
 * If the user executes a drag bigger than MINDRAG, callbacks will fire as:
 *      prepFn, moveFn (1 or more times), doneFn
 * If the user does not drag enough, prepFn and clickFn will fire.
 *
 * Note: If you cancel contextmenu, clickFn will fire even with a right click
 * (unlike native events) so you'll get a `plotly_click` event. Cancel context eg:
 *    gd.addEventListener('contextmenu', function(e) { e.preventDefault(); });
 * TODO: we should probably turn this into a `config` parameter, so we can fix it
 * such that if you *don't* cancel contextmenu, we can prevent partial drags, which
 * put you in a weird state.
 *
 * If the user clicks multiple times quickly, clickFn will fire each time
 * but numClicks will increase to help you recognize doubleclicks.
 *
 * @param {object} options with keys:
 *      element (required) the DOM element to drag
 *      prepFn (optional) function(event, startX, startY)
 *          executed on mousedown
 *          startX and startY are the clientX and clientY pixel position
 *          of the mousedown event
 *      moveFn (optional) function(dx, dy)
 *          executed on move, ONLY after we've exceeded MINDRAG
 *          (we keep executing moveFn if you move back to where you started)
 *          dx and dy are the net pixel offset of the drag,
 *          dragged is true/false, has the mouse moved enough to
 *          constitute a drag
 *      doneFn (optional) function(e)
 *          executed on mouseup, ONLY if we exceeded MINDRAG (so you can be
 *          sure that moveFn has been called at least once)
 *          numClicks is how many clicks we've registered within
 *          a doubleclick time
 *          e is the original mouseup event
 *      clickFn (optional) function(numClicks, e)
 *          executed on mouseup if we have NOT exceeded MINDRAG (ie moveFn
 *          has not been called at all)
 *          numClicks is how many clicks we've registered within
 *          a doubleclick time
 *          e is the original mousedown event
 *      clampFn (optional, function(dx, dy) return [dx2, dy2])
 *          Provide custom clamping function for small displacements.
 *          By default, clamping is done using `minDrag` to x and y displacements
 *          independently.

/**
 * Tweak to Array.sort(sortFn) that improves performance for pre-sorted arrays
 *
 * Note that newer browsers (such as Chrome v70+) are starting to pick up
 * on pre-sorted arrays which may render the following optimization unnecessary
 * in the future.
 *
 * Motivation: sometimes we need to sort arrays but the input is likely to
 * already be sorted. Browsers don't seem to pick up on pre-sorted arrays,
 * and in fact Chrome is actually *slower* sorting pre-sorted arrays than purely
 * random arrays. FF is at least faster if the array is pre-sorted, but still
 * not as fast as it could be.
 * Here's how this plays out sorting a length-1e6 array:
 *
 * Calls to Sort FN  |  Chrome bare  |  FF bare  |  Chrome tweak  |  FF tweak
 *                   |  v68.0 Mac    |  v61.0 Mac|                |
 * ------------------+---------------+-----------+----------------+------------
 * ordered           |  30.4e6       |  10.1e6   |  1e6           |  1e6
 * reversed          |  29.4e6       |  9.9e6    |  1e6 + reverse |  1e6 + reverse
 * random            |  ~21e6        |  ~18.7e6  |  ~21e6         |  ~18.7e6
 *
 * So this is a substantial win for pre-sorted (ordered or exactly reversed)
 * arrays. Including this wrapper on an unsorted array adds a penalty that will
 * in general be only a few calls to the sort function. The only case this
 * penalty will be significant is if the array is mostly sorted but there are
 * a few unsorted items near the end, but the penalty is still at most N calls
 * out of (for N=1e6) ~20N total calls
 *
 * @param {Array} array: the array, to be sorted in place
 * @param {function} sortFn: As in Array.sort, function(a, b) that puts
 *     item a before item b if the return is negative, a after b if positive,
 *     and no change if zero.
 * @return {Array}: the original array, sorted in place.

 *
 * You can combine many edits to different objects. Objects are added and edited
 * in ascending order, then removed in descending order.
 * For example, starting with [a, b, c], if you want to:
 * - replace b with d:
 *   {'annotations[1]': d, 'annotations[2]': null} (b is item 2 after adding d)
 * - add a new item d between a and b, and edit b:

 * - delete b and edit c:
 *    {'annotations[1]': null, 'annotations[2].x': newX} (c is edited before b is removed)
 *
 * You CANNOT combine adding/deleting an item at index `i` with edits to the same index `i`
 * You CANNOT combine replacing/deleting the whole array with anything else (for the same array).

 * findExtremes
 *
 * Find min/max extremes of an array of coordinates on a given axis.
 *
 * Note that findExtremes is called during `calc`, when we don't yet know the axis
 * length; all the inputs should be based solely on the trace data, nothing
 * about the axis layout.
 *
 * Note that `ppad` and `vpad` as well as their asymmetric variants refer to
 * the before and after padding of the passed `data` array, not to the whole axis.
 *
 * @param {object} ax: full axis object
 *   relies on
 *   - ax.type
 *   - ax._m (just its sign)
 *   - ax.d2l
 * @param {array} data:
 *  array of numbers (i.e. already run though ax.d2c)
 * @param {object} opts:
 *  available keys are:
 *      vpad: (number or number array) pad values (data value +-vpad)
 *      ppad: (number or number array) pad pixels (pixel location +-ppad)
 *      ppadplus, ppadminus, vpadplus, vpadminus:
 *          separate padding for each side, overrides symmetric
 *      padded: (boolean) add 5% padding to both ends
 *          (unless one end is overridden by tozero)
 *      tozero: (boolean) make sure to include zero if axis is linear,
 *          and make it a tight bound if possible
 *      vpadLinearized: (boolean) whether or not vpad (or vpadplus/vpadminus)
 *          is linearized (for log scale axes)
 *
 * @return {object}
 *  - min {array of objects}
 *  - max {array of objects}
 *  each object item has fields:
 *    - val {number}
 *    - pad {number}
 *    - extrappad {number}
 *  - opts {object}: a ref to the passed "options" object

 * @param {object} fullLayout

 *
 * Here, reuse some of the Cartesian setConvert logic,
 * but we must extend some of it, as both radial and angular axes
 * don't have domains and angular axes don't have _true_ ranges.
 *
 * Moreover, we introduce two new coordinate systems:
 * - 'g' for geometric coordinates and
 * - 't' for angular ticks
 *
 * Radial axis coordinate systems:
 * - d, c and l: same as for cartesian axes
 * - g: like calcdata but translated about `radialaxis.range[0]` & `polar.hole`
 *
 * Angular axis coordinate systems:
 * - d: data, in whatever form it's provided
 * - c: calcdata, turned into radians (for linear axes)
 *      or category indices (category axes)
 * - t: tick calcdata, just like 'c' but in degrees for linear axes
 * - g: geometric calcdata, radians coordinates that take into account
 *      axis rotation and direction
 *
 * Then, 'g'eometric data is ready to be converted to (x,y).

/*
 * Evaluates the derivative of a list of control point arrays. That is, it expects an array or arrays
 * that are expanded relative to the raw data to include the bicubic control points, if applicable. If
 * only linear interpolation is desired, then the data points correspond 1-1 along that axis to the
 * data itself. Since it's catmull-rom splines in either direction note in particular that the
 * derivatives are discontinuous across cell boundaries. That's the reason you need both the *cell*
 * and the *point within the cell*.
 *
 * Also note that the discontinuity of the derivative is in magnitude only. The direction *is*
 * continuous across cell boundaries.
 *
 * For example, to compute the derivative of the xcoordinate halfway between the 7 and 8th i-gridpoints
 * and the 10th and 11th j-gridpoints given bicubic smoothing in both dimensions, you'd write:
 *
 *     var deriv = createIDerivativeEvaluator([x], 1, 1);
 *
 *     var dxdi = deriv([], 7, 10, 0.5, 0.5);
 *     // => [0.12345]
 *
 * Since there'd be a bunch of duplicate computation to compute multiple derivatives, you can double
 * this up by providing more arrays:
 *
 *     var deriv = createIDerivativeEvaluator([x, y], 1, 1);
 *
 *     var dxdi = deriv([], 7, 10, 0.5, 0.5);
 *     // => [0.12345, 0.78910]
 *
 * NB: It's presumed that at this point all data has been sanitized and is valid numerical data arrays
 * of the correct dimension.

 * In mathematical terms, Mapbox GL heatmaps are a bivariate (2D) kernel density
 * estimation with a Gaussian kernel. It means that each data point has an area
 * of “influence” around it (called a kernel) where the numerical value of
 * influence (which we call density) decreases as you go further from the point.
 * If we sum density values of all points in every pixel of the screen, we get a
 * combined density value which we then map to a heatmap color.

// Why go through the trouble of using a uniqueness hash table vs
// sort and uniq:
//
// Suppose you've got a million positions in a 100x100x100 grid.
//
// Using a uniqueness hash table, you're doing 1M array reads,
// 3M hash table lookups from 100-element hashes, 300 hash table inserts, then
// sorting three 100-element arrays and iterating over them.
// Roughly, 1M + 3M * ln(100) + 300 * ln(100/2) + 3 * 100 * ln(100) + 3 * 100 =
//          1M + 13.8M + 0.0012M +  0.0014M + 0.0003M
//          =~ 15M
//
// Sort and uniq solution would do 1M array reads, 3M array inserts,
// sort three 1M-element arrays and iterate over them.
// Roughly, 1M + 3M + 3 * 1M * ln(1M) + 3 * 1M =
//          1M + 3M + 41.4M + 3M
//          =~ 48.4M
//
// Guessing that a hard-coded sort & uniq would be faster due to not having
// to run a hashing function on everything. More memory usage though
// (bunch of small hash tables vs. duplicating the input array.)
//
// In JS-land, who knows. Maybe xi[x] casts x to string and destroys perf,
// maybe numeric keys get special-cased, maybe the object lookups run at near O(1)-speeds.
// Maybe the sorting comparison function is expensive to call, maybe it gets inlined or special-cased.
//
// ... You're probably not going to call this with more than 10k positions anyhow, so this is very academic.

 * @fileoverview Install a leaky WeakMap emulation on platforms that
 * don't provide a built-in one.
 *
 * <p>Assumes that an ES5 platform where, if {@code WeakMap} is
 * already present, then it conforms to the anticipated ES6
 * specification. To run this file on an ES5 or almost ES5
 * implementation where the {@code WeakMap} specification does not
 * quite conform, run <code>repairES5.js</code> first.
 *
 * <p>Even though WeakMapModule is not global, the linter thinks it
 * is, which is why it is in the overrides list below.
 *
 * <p>NOTE: Before using this WeakMap emulation in a non-SES
 * environment, see the note below about hiddenRecord.
 *
 * @author Mark S. Miller
 * @requires crypto, ArrayBuffer, Uint8Array, navigator, console
 * @overrides WeakMap, ses, Proxy
 * @overrides WeakMapModule
 */ /**
 * This {@code WeakMap} emulation is observably equivalent to the
 * ES-Harmony WeakMap, but with leakier garbage collection properties.
 *
 * <p>As with true WeakMaps, in this emulation, a key does not
 * retain maps indexed by that key and (crucially) a map does not
 * retain the keys it indexes. A map by itself also does not retain
 * the values associated with that map.
 *
 * <p>However, the values associated with a key in some map are
 * retained so long as that key is retained and those associations are
 * not overridden. For example, when used to support membranes, all
 * values exported from a given membrane will live for the lifetime
 * they would have had in the absence of an interposed membrane. Even
 * when the membrane is revoked, all objects that would have been
 * reachable in the absence of revocation will still be reachable, as
 * far as the GC can tell, even though they will no longer be relevant
 * to ongoing computation.
 *
 * <p>The API implemented here is approximately the API as implemented
 * in FF6.0a1 and agreed to by MarkM, Andreas Gal, and Dave Herman,
 * rather than the offially approved proposal page. TODO(erights):
 * upgrade the ecmascript WeakMap proposal page to explain this API
 * change and present to EcmaScript committee for their approval.
 *
 * <p>The first difference between the emulation here and that in
 * FF6.0a1 is the presence of non enumerable {@code get___, has___,
 * set___, and delete___} methods on WeakMap instances to represent
 * what would be the hidden internal properties of a primitive
 * implementation. Whereas the FF6.0a1 WeakMap.prototype methods
 * require their {@code this} to be a genuine WeakMap instance (i.e.,
 * an object of {@code [[Class]]} "WeakMap}), since there is nothing
 * unforgeable about the pseudo-internal method names used here,
 * nothing prevents these emulated prototype methods from being
 * applied to non-WeakMaps with pseudo-internal methods of the same
 * names.
 *
 * <p>Another difference is that our emulated {@code
 * WeakMap.prototype} is not itself a WeakMap. A problem with the
 * current FF6.0a1 API is that WeakMap.prototype is itself a WeakMap
 * providing ambient mutability and an ambient communications
 * channel. Thus, if a WeakMap is already present and has this
 * problem, repairES5.js wraps it in a safe wrappper in order to
 * prevent access to this channel. (See
 * PATCH_MUTABLE_FROZEN_WEAKMAP_PROTO in repairES5.js).
 */ /**
 * If this is a full <a href=
 * "http://code.google.com/p/es-lab/wiki/SecureableES5"
 * >secureable ES5</a> platform and the ES-Harmony {@code WeakMap} is
 * absent, install an approximate emulation.
 *
 * <p>If WeakMap is present but cannot store some objects, use our approximate
 * emulation as a wrapper.
 *
 * <p>If this is almost a secureable ES5 platform, then WeakMap.js
 * should be run after repairES5.js.
 *
 * <p>See {@code WeakMap} for documentation of the garbage collection
 * properties of this WeakMap emulation.

   *
   * <p>It is the monkey patching logic in this file that is intended

   * three fundamental means of discovering properties of an object:
   * The for/in loop, Object.keys(), and Object.getOwnPropertyNames(),
   * as well as some proposed ES6 extensions that appear on our
   * whitelist. The first two only discover enumerable properties, and
   * we only use HIDDEN_NAME to name a non-enumerable property, so the
   * only remaining threat should be getOwnPropertyNames and some
   * proposed ES6 extensions that appear on our whitelist. We monkey
   * patch them to remove HIDDEN_NAME from the list of properties they
   * returns.
   *
   * <p>TODO(erights): On a platform with built-in Proxies, proxies
   * could be used to trap and thereby discover the HIDDEN_NAME, so we
   * need to monkey patch Proxy.create, Proxy.createFunction, etc, in
   * order to wrap the provided handler with the real handler which
   * filters out all traps using HIDDEN_NAME.
   *
   * <p>TODO(erights): Revisit Mike Stay's suggestion that we use an
   * encapsulated function at a not-necessarily-secret name, which
   * uses the Stiegler shared-state rights amplification pattern to
   * reveal the associated value only to the WeakMap in which this key
   * is associated with that value. Since only the key retains the
   * function, the function can also remember the key without causing
   * leakage of the key, so this doesn't violate our general gc
   * goals. In addition, because the name need not be a guarded
   * secret, we could efficiently handle cross-frame frozen keys.

   * <ul>
   * <li>Making the name of the hidden property unguessable, so "[]"

   * <li>Making the hidden property non-enumerable, so we need not

 * Is this string all whitespace?

 * and verified with:
 *
 *  for(var i = 0; i < 65536; i++) {
 *      var s = String.fromCharCode(i);
 *      if(+s===0 && !s.trim()) console.log(i, s);
 *  }
 *

 * that *is* whitespace. Note that charCodeAt stops at 16 bits, but it appears
 * that there are no whitespace characters above this, and code points above
 * this do not map onto white space characters.

// a transform stream is a readable/writable stream where you do
// something with the data.  Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored.  (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation.  For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes.  When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up.  When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer.  When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks.  If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk.  However,
// a pathological inflate type of transform can cause excessive buffering
// here.  For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output.  In this case, you could write a very small
// amount of input, and end up with a very large amount of output.  In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform.  A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.

/**
 * CSS color parser compliant with CSS Color 4 Specification.
 * Supports: named colors, `transparent` keyword, all rgb hex notations,
 * rgb(), rgba(), hsl() and hsla() functions.
 * Does not round the parsed values to integers from the range 0..255.
 *
 * Syntax:
 *
 * <alpha-value> = <number> | <percentage>
 *         <hue> = <number> | <angle>
 *
 *         rgb() = rgb( <percentage>{3} [ / <alpha-value> ]? ) | rgb( <number>{3} [ / <alpha-value> ]? )
 *         rgb() = rgb( <percentage>#{3} , <alpha-value>? )    | rgb( <number>#{3} , <alpha-value>? )
 *
 *         hsl() = hsl( <hue> <percentage> <percentage> [ / <alpha-value> ]? )
 *         hsl() = hsl( <hue>, <percentage>, <percentage>, <alpha-value>? )
 *
 * Caveats:
 *   - <angle> - <number> with optional `deg` suffix; `grad`, `rad`, `turn` are not supported
 *   - `none` keyword is not supported
 *   - comments inside rgb()/hsl() are not supported
 *   - legacy color syntax rgba() is supported with an identical grammar and behavior to rgb()
 *   - legacy color syntax hsla() is supported with an identical grammar and behavior to hsl()
 *

/**
 * Returns a ratio that can be used to interpolate between exponential function
 * stops.
 * How it works: Two consecutive stop values define a (scaled and shifted) exponential function `f(x) = a * base^x + b`, where `base` is the user-specified base,
 * and `a` and `b` are constants affording sufficient degrees of freedom to fit
 * the function to the given stops.
 *
 * Here's a bit of algebra that lets us compute `f(x)` directly from the stop
 * values without explicitly solving for `a` and `b`:
 *
 * First stop value: `f(x0) = y0 = a * base^x0 + b`
 * Second stop value: `f(x1) = y1 = a * base^x1 + b`
 * => `y1 - y0 = a(base^x1 - base^x0)`
 * => `a = (y1 - y0)/(base^x1 - base^x0)`
 *
 * Desired value: `f(x) = y = a * base^x + b`
 * => `f(x) = y0 + a * (base^x - base^x0)`
 *
 * From the above, we can replace the `a` in `a * (base^x - base^x0)` and do a
 * little algebra:
 * ```
 * a * (base^x - base^x0) = (y1 - y0)/(base^x1 - base^x0) * (base^x - base^x0)
 *                     = (y1 - y0) * (base^x - base^x0) / (base^x1 - base^x0)
 * ```
 *
 * If we let `(base^x - base^x0) / (base^x1 base^x0)`, then we have
 * `f(x) = y0 + (y1 - y0) * ratio`.  In other words, `ratio` may be treated as
 * an interpolation factor between the two stops' output values.
 *
 * (Note: a slightly different form for `ratio`,
 * `(base^(x-x0) - 1) / (base^(x1-x0) - 1) `, is equivalent, but requires fewer
 * expensive `Math.pow()` operations.)

/**
 * Returns a ratio that can be used to interpolate between exponential function
 * stops.
 *
 * How it works:
 * Two consecutive stop values define a (scaled and shifted) exponential
 * function `f(x) = a * base^x + b`, where `base` is the user-specified base,
 * and `a` and `b` are constants affording sufficient degrees of freedom to fit
 * the function to the given stops.
 *
 * Here's a bit of algebra that lets us compute `f(x)` directly from the stop
 * values without explicitly solving for `a` and `b`:
 *
 * First stop value: `f(x0) = y0 = a * base^x0 + b`
 * Second stop value: `f(x1) = y1 = a * base^x1 + b`
 * => `y1 - y0 = a(base^x1 - base^x0)`
 * => `a = (y1 - y0)/(base^x1 - base^x0)`
 *
 * Desired value: `f(x) = y = a * base^x + b`
 * => `f(x) = y0 + a * (base^x - base^x0)`
 *
 * From the above, we can replace the `a` in `a * (base^x - base^x0)` and do a
 * little algebra:
 * ```
 * a * (base^x - base^x0) = (y1 - y0)/(base^x1 - base^x0) * (base^x - base^x0)
 *                     = (y1 - y0) * (base^x - base^x0) / (base^x1 - base^x0)
 * ```
 *
 * If we let `(base^x - base^x0) / (base^x1 base^x0)`, then we have
 * `f(x) = y0 + (y1 - y0) * ratio`.  In other words, `ratio` may be treated as
 * an interpolation factor between the two stops' output values.
 *
 * (Note: a slightly different form for `ratio`,
 * `(base^(x-x0) - 1) / (base^(x1-x0) - 1) `, is equivalent, but requires fewer
 * expensive `Math.pow()` operations.)

 * `StructArray` provides an abstraction over `ArrayBuffer` and `TypedArray`

 *
 * Conceptually, a StructArray is comprised of elements, i.e., instances of its
 * associated struct type. Each particular struct type, together with an
 * alignment size, determines the memory layout of a StructArray whose elements
 * are of that type.  Thus, for each such layout that we need, we have
 * a corresponding StructArrayLayout class, inheriting from StructArray and
 * implementing `emplaceBack()` and `_refreshViews()`.
 *
 * In some cases, where we need to access particular elements of a StructArray,
 * we implement a more specific subclass that inherits from one of the
 * StructArrayLayouts and adds a `get(i): T` accessor that returns a structured
 * object whose properties are proxies into the underlying memory space for the
 * i-th element.  This affords the convenience of working with (seemingly) plain
 * Javascript objects without the overhead of serializing/deserializing them

/**
 * @internal
 * ProgramConfiguration contains the logic for binding style layer properties and tile
 * layer feature data into GL program uniforms and vertex attributes.
 *
 * Non-data-driven property values are bound to shader uniforms. Data-driven property
 * values are bound to vertex attributes. In order to support a uniform GLSL syntax over
 * both, [Mapbox GL Shaders](https://github.com/mapbox/mapbox-gl-shaders) defines a `#pragma`
 * abstraction, which ProgramConfiguration is responsible for implementing. At runtime,
 * it examines the attributes of a particular layer, combines this with fixed knowledge
 * about how layers of the particular type are implemented, and determines which uniforms
 * and vertex attributes will be required. It can then substitute the appropriate text
 * into the shader source code, create and link a program, and bind the uniforms and
 * vertex attributes in preparation for drawing.
 *
 * When a vector tile is parsed, this same configuration information is used to
 * populate the attribute buffers needed for data-driven styling using the zoom
 * level and feature property data.

/**
 * @internal
 * Unlike other buckets, which simply implement #addFeature with type-specific
 * logic for (essentially) triangulating feature geometries, SymbolBucket
 * requires specialized behavior:
 *
 * 1. WorkerTile#parse(), the logical owner of the bucket creation process,
 *    calls SymbolBucket#populate(), which resolves text and icon tokens on
 *    each feature, adds each glyphs and symbols needed to the passed-in
 *    collections options.glyphDependencies and options.iconDependencies, and
 *    stores the feature data for use in subsequent step (this.features).
 *
 * 2. WorkerTile asynchronously requests from the main thread all of the glyphs
 *    and icons needed (by this bucket and any others). When glyphs and icons
 *    have been received, the WorkerTile creates a CollisionIndex and invokes:
 *
 * 3. performSymbolLayout(bucket, stacks, icons) perform texts shaping and
 *    layout on a Symbol Bucket. This step populates:
 *      `this.symbolInstances`: metadata on generated symbols
 *      `this.collisionBoxArray`: collision data for use by foreground
 *      `this.text`: SymbolBuffers for text symbols
 *      `this.icons`: SymbolBuffers for icons
 *      `this.iconCollisionBox`: Debug SymbolBuffers for icon collision boxes
 *      `this.textCollisionBox`: Debug SymbolBuffers for text collision boxes
 *    The results are sent to the foreground for rendering
 *
 * 4. placement.ts is run on the foreground,
 *    and uses the CollisionIndex along with current camera settings to determine
 *    which symbols can actually show on the map. Collided symbols are hidden
 *    using a dynamic "OpacityVertexArray".

 *
 * - the size of 1 unit is the width of the projected world instead of the "mercator meter"
 * - the origin of the coordinate space is at the north-west corner instead of the middle
 *
 * For example, `MercatorCoordinate(0, 0, 0)` is the north-west corner of the mercator world and

 *
 * The `z` dimension of `MercatorCoordinate` is conformal. A cube in the mercator coordinate space would be rendered as a cube.

/**
 * By default, the image queue is self driven, meaning as soon as one requested item is processed,

 * the number of concurrent requests to MAX_PARALLEL_IMAGE_REQUESTS. The default behavior
 * ensures that static views of the map can be rendered with minimal delay.
 *
 * However, the default behavior can prevent dynamic views of the map from rendering
 * smoothly in that many requests can finish in one render frame, putting too much pressure on GPU.
 *
 * When the view of the map is moving dynamically, smoother frame rates can be achieved
 * by throttling the number of items processed by the queue per frame. This can be
 * accomplished by using {@link addThrottleControl} to allow the caller to
 * use a lambda function to determine when the queue should be throttled (e.g. when isMoving())

/*
 * # Overview of coordinate spaces
 *
 * ## Tile coordinate spaces
 * Each label has an anchor. Some labels have corresponding line geometries.
 * The points for both anchors and lines are stored in tile units. Each tile has it's own
 * coordinate space going from (0, 0) at the top left to (EXTENT, EXTENT) at the bottom right.
 *
 * ## Clip space (GL coordinate space)
 * At the end of everything, the vertex shader needs to produce a position in clip space,
 * which is (-1, 1) at the top left and (1, -1) in the bottom right.
 * In the depth buffer, values are between 0 (near plane) to 1 (far plane).
 *
 * ## Map pixel coordinate spaces
 * Each tile has a pixel coordinate space. It's just the tile units scaled so that one unit is
 * whatever counts as 1 pixel at the current zoom.
 * This space is used for pitch-alignment=map, rotation-alignment=map
 *
 * ## Rotated map pixel coordinate spaces
 * Like the above, but rotated so axis of the space are aligned with the viewport instead of the tile.
 * This space is used for pitch-alignment=map, rotation-alignment=viewport
 *
 * ## Viewport pixel coordinate space
 * (0, 0) is at the top left of the canvas and (pixelWidth, pixelHeight) is at the bottom right corner
 * of the canvas. This space is used for pitch-alignment=viewport
 *
 *
 * # Vertex projection
 * It goes roughly like this:
 * 1. project the anchor and line from tile units into the correct label coordinate space
 *      - map pixel space           pitch-alignment=map         rotation-alignment=map
 *      - rotated map pixel space   pitch-alignment=map         rotation-alignment=viewport
 *      - viewport pixel space      pitch-alignment=viewport    rotation-alignment=*
 * 2. if the label follows a line, find the point along the line that is the correct distance from the anchor.
 * 3. add the glyph's corner offset to the point from step 3
 * 4. convert from the label coordinate space to clip space
 *
 * For horizontal labels we want to do step 1 in the shader for performance reasons (no cpu work).
 *      This is what `u_label_plane_matrix` is used for.
 * For labels aligned with lines we have to steps 1 and 2 on the cpu since we need access to the line geometry.
 *      This is what `updateLineLabels(...)` does.
 *      Since the conversion is handled on the cpu we just set `u_label_plane_matrix` to an identity matrix.
 *
 * Steps 3 and 4 are done in the shaders for all labels.

/*
    The CrossTileSymbolIndex generally works on the assumption that
    a conceptual "unique symbol" can be identified by the text of
    the label combined with the anchor point. The goal is to assign
    these conceptual "unique symbols" a shared crossTileID that can be
    used by Placement to keep fading opacity states consistent and to
    deduplicate labels.

    The CrossTileSymbolIndex indexes all the current symbol instances and
    their crossTileIDs. When a symbol bucket gets added or updated, the
    index assigns a crossTileID to each of it's symbol instances by either
    matching it with an existing id or assigning a new one.

/**
 * @internal
 * This is the main class which handles most of the 3D Terrain logic. It has the following topics:
 *
 * 1. loads raster-dem tiles via the internal sourceCache this.sourceCache
 * 2. creates a depth-framebuffer, which is used to calculate the visibility of coordinates
 * 3. creates a coords-framebuffer, which is used the get to tile-coordinate for a screen-pixel
 * 4. stores all render-to-texture tiles in the this.sourceCache._tiles
 * 5. calculates the elevation for a specific tile-coordinate
 * 6. creates a terrain-mesh
 *
 * A note about the GPU resource-usage:
 *
 * Framebuffers:
 *
 * - one for the depth & coords framebuffer with the size of the map-div.
 * - one for rendering a tile to texture with the size of tileSize (= 512x512).
 *
 * Textures:
 *
 * - one texture for an empty raster-dem tile with size 1x1
 * - one texture for an empty depth-buffer, when terrain is disabled with size 1x1
 * - one texture for an each loaded raster-dem with size of the source.tileSize
 * - one texture for the coords-framebuffer with the size of the map-div.
 * - one texture for the depth-framebuffer with the size of the map-div.
 * - one texture for the encoded tile-coords with the size 2*tileSize (=1024x1024)
 * - finally for each render-to-texture tile (= this._tiles) a set of textures
 * for each render stack (The stack-concept is documented in painter.ts).
 *
 * Normally there exists 1-3 Textures per tile, depending on the stylesheet.
 * Each Textures has the size 2*tileSize (= 1024x1024). Also there exists a
 * cache of the last 150 newest rendered tiles.

 * The `Map` object represents the map on your page. It exposes methods

 *
 * You create a `Map` by specifying a `container` and other options, see {@link MapOptions} for the full list.
 * Then MapLibre GL JS initializes the map on the page and returns your `Map` object.
 *
 * @group Main

 * @example
 * ```ts

    /**
     * Returns an array of MapGeoJSONFeature objects
     * representing visible features that satisfy the query parameters.
     *
     * @param geometryOrOptions - (optional) The geometry of the query region:
     * either a single point or southwest and northeast points describing a bounding box.
     * Omitting this parameter (i.e. calling {@link Map#queryRenderedFeatures} with zero arguments,
     * or with only a `options` argument) is equivalent to passing a bounding box encompassing the entire
     * map viewport.
     * The geometryOrOptions can receive a {@link QueryRenderedFeaturesOptions} only to support a situation where the function receives only one parameter which is the options parameter.
     * @param options - (optional) Options object.
     *
     * @returns An array of MapGeoJSONFeature objects.
     *
     * The `properties` value of each returned feature object contains the properties of its source feature. For GeoJSON sources, only
     * string and numeric property values are supported (i.e. `null`, `Array`, and `Object` values are not supported).
     *
     * Each feature includes top-level `layer`, `source`, and `sourceLayer` properties. The `layer` property is an object
     * representing the style layer to  which the feature belongs. Layout and paint properties in this object contain values
     * which are fully evaluated for the given zoom level and feature.
     *
     * Only features that are currently rendered are included. Some features will **not** be included, like:
     *
     * - Features from layers whose `visibility` property is `"none"`.
     * - Features from layers whose zoom range excludes the current zoom level.
     * - Symbol features that have been hidden due to text or icon collision.
     *
     * Features from all other layers are included, including features that may have no visible
     * contribution to the rendered result; for example, because the layer's opacity or color alpha component is set to
     * 0.
     *
     * The topmost rendered feature appears first in the returned array, and subsequent features are sorted by
     * descending z-order. Features that are rendered multiple times (due to wrapping across the antemeridian at low
     * zoom levels) are returned only once (though subject to the following caveat).
     *
     * Because features come from tiled vector data or GeoJSON data that is converted to tiles internally, feature
     * geometries may be split or duplicated across tile boundaries and, as a result, features may appear multiple
     * times in query results. For example, suppose there is a highway running through the bounding rectangle of a query.
     * The results of the query will be those parts of the highway that lie within the map tiles covering the bounding
     * rectangle, even if the highway extends into other tiles, and the portion of the highway within each map tile
     * will be returned as a separate feature. Similarly, a point feature near a tile boundary may appear in multiple
     * tiles due to tile buffering.
     *
     * @example
     * Find all features at a point
     * ```ts
     * let features = map.queryRenderedFeatures(
     *   [20, 35],
     *   { layers: ['my-layer-name'] }
     * );
     * ```
     *
     * @example
     * Find all features within a static bounding box
     * ```ts
     * let features = map.queryRenderedFeatures(
     *   [[10, 20], [30, 50]],
     *   { layers: ['my-layer-name'] }
     * );
     * ```
     *
     * @example
     * Find all features within a bounding box around a point
     * ```ts
     * let width = 10;
     * let height = 20;
     * let features = map.queryRenderedFeatures([
     *   [point.x - width / 2, point.y - height / 2],
     *   [point.x + width / 2, point.y + height / 2]
     * ], { layers: ['my-layer-name'] });
     * ```
     *
     * @example
     * Query all rendered features from a single layer
     * ```ts
     * let features = map.queryRenderedFeatures({ layers: ['my-layer-name'] });

     * vector tiles and GeoJSON source tiles: this function does not check tiles outside the currently
     * visible viewport.
     *
     * Because features come from tiled vector data or GeoJSON data that is converted to tiles internally, feature
     * geometries may be split or duplicated across tile boundaries and, as a result, features may appear multiple
     * times in query results. For example, suppose there is a highway running through the bounding rectangle of a query.
     * The results of the query will be those parts of the highway that lie within the map tiles covering the bounding
     * rectangle, even if the highway extends into other tiles, and the portion of the highway within each map tile
     * will be returned as a separate feature. Similarly, a point feature near a tile boundary may appear in multiple
     * tiles due to tile buffering.
     *
     * @example
     * Find all features in one source layer in a vector source

     * Sets the `state` of a feature.

     * When using this method, the `state` object is merged with any existing key-value pairs in the feature's state.
     * Features are identified by their `feature.id` attribute, which can be any number or string.
     *
     * This method can only be used with sources that have a `feature.id` attribute. The `feature.id` attribute can be defined in three ways:
     *
     * - For vector or GeoJSON sources, including an `id` attribute in the original data file.
     * - For vector or GeoJSON sources, using the [`promoteId`](https://maplibre.org/maplibre-style-spec/sources/#vector-promoteId) option at the time the source is defined.
     * - For GeoJSON sources, using the [`generateId`](https://maplibre.org/maplibre-style-spec/sources/#geojson-generateId) option to auto-assign an `id` based on the feature's index in the source data. If you change feature data using `map.getSource('some id').setData(..)`, you may need to re-apply state taking into account updated `id` values.
     *
     * _Note: You can use the [`feature-state` expression](https://maplibre.org/maplibre-style-spec/expressions/#feature-state) to access the values in a feature's state object for the purposes of styling._
     *
     * @param feature - Feature identifier. Feature objects returned from
     * {@link Map#queryRenderedFeatures} or event handlers can be used as feature identifiers.
     * @param state - A set of key-value pairs. The values should be valid JSON types.
     *
     * @example
     * ```ts
     * // When the mouse moves over the `my-layer` layer, update
     * // the feature state for the feature under the mouse

/**
 * A `GeolocateControl` control provides a button that uses the browser's geolocation
 * API to locate the user on the map.
 *
 * Not all browsers support geolocation,
 * and some users may disable the feature. Geolocation support for modern
 * browsers including Chrome requires sites to be served over HTTPS. If
 * geolocation support is not available, the `GeolocateControl` will show
 * as disabled.
 *
 * The zoom level applied will depend on the accuracy of the geolocation provided by the device.
 *
 * The `GeolocateControl` has two modes. If `trackUserLocation` is `false` (default) the control acts as a button, which when pressed will set the map's camera to target the user location. If the user moves, the map won't update. This is most suited for the desktop. If `trackUserLocation` is `true` the control acts as a toggle button that when active the user's location is actively monitored for changes. In this mode the `GeolocateControl` has three interaction states:
 * * active - the map's camera automatically updates as the user's location changes, keeping the location dot in the center. Initial state and upon clicking the `GeolocateControl` button.
 * * passive - the user's location dot automatically updates, but the map's camera does not. Occurs upon the user initiating a map movement.
 * * disabled - occurs if Geolocation is not available, disabled or denied.
 *
 * These interaction states can't be controlled programmatically, rather they are set based on user interactions.
 *
 * ## State Diagram
 * ![GeolocateControl state diagram](https://github.com/maplibre/maplibre-gl-js/assets/3269297/78e720e5-d781-4da8-9803-a7a0e6aaaa9f)
 *
 * @group Markers and Controls
 *
 * @example
 * ```ts
 * map.addControl(new GeolocateControl({
 *     positionOptions: {
 *         enableHighAccuracy: true
 *     },
 *     trackUserLocation: true
 * }));
 * ```
 * @see [Locate the user](https://maplibre.org/maplibre-gl-js/docs/examples/locate-user/)
 *
 * ## Events
 *
 * **Event** `trackuserlocationend` of type {@link Event} will be fired when the `GeolocateControl` changes to the background state, which happens when a user changes the camera during an active position lock. This only applies when `trackUserLocation` is `true`. In the background state, the dot on the map will update with location updates but the camera will not.
 *
 * **Event** `trackuserlocationstart` of type {@link Event} will be fired when the `GeolocateControl` changes to the active lock state, which happens either upon first obtaining a successful Geolocation API position for the user (a `geolocate` event will follow), or the user clicks the geolocate button when in the background state which uses the last known position to recenter the map and enter active lock state (no `geolocate` event will follow unless the users's location changes).
 *
 * **Event** `userlocationlostfocus` of type {@link Event} will be fired when the `GeolocateControl` changes to the background state, which happens when a user changes the camera during an active position lock. This only applies when `trackUserLocation` is `true`. In the background state, the dot on the map will update with location updates but the camera will not.
 *
 * **Event** `userlocationfocus` of type {@link Event} will be fired when the `GeolocateControl` changes to the active lock state, which happens upon the user clicks the geolocate button when in the background state which uses the last known position to recenter the map and enter active lock state.
 *
 * **Event** `geolocate` of type {@link Event} will be fired on each Geolocation API position update which returned as success.
 * `data` - The returned [Position](https://developer.mozilla.org/en-US/docs/Web/API/Position) object from the callback in [Geolocation.getCurrentPosition()](https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/getCurrentPosition) or [Geolocation.watchPosition()](https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/watchPosition).
 *
 * **Event** `error` of type {@link Event} will be fired on each Geolocation API position update which returned as an error.
 * `data` - The returned [PositionError](https://developer.mozilla.org/en-US/docs/Web/API/PositionError) object from the callback in [Geolocation.getCurrentPosition()](https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/getCurrentPosition) or [Geolocation.watchPosition()](https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/watchPosition).
 *
