/**
 * 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:

 * - 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).

 * the before and after padding of the passed `data` array, not to the whole axis.
 *

 *   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}

 *                    optionally with a country/region code ('en-GB', 'de-CH'). If a country

 *  - dictionary {object} : the dictionary mapping input strings to localized strings
 *                          generally the keys should be the literal input strings, but
 *                          if default translations are provided you can use any string as a key.
 *  - format {object} : a `d3.locale` format specifier for this locale
 *                      any omitted keys we'll fall back on en-US.
 *
 *  A valid `moduleType: 'transform'` module has fields:

 *  - calcTransform {function} : calc-level transform function
 *  - attributes {object} : transform attributes declarations
 *  - supplyDefaults {function} : attributes default-supply function
 *
 *  A valid `moduleType: 'component'` module has fields:
 *  - name {string} : the component name, used it with Register.getComponentMethod()
 *                    to employ component method.
 *
 *  A valid `moduleType: 'apiMethod'` module has fields:
 *  - name {string} : the api method name.
