/*
 * @class Point
 * @aka L.Point
 *
 * Represents a point with `x` and `y` coordinates in pixels.
 *
 * @example
 *
 * ```js
 * var point = L.point(200, 300);
 * ```
 *
 * All Leaflet methods and options that accept `Point` objects also accept them in a simple Array form (unless noted otherwise), so these lines are equivalent:
 *
 * ```js
 * map.panBy([200, 300]);
 * map.panBy(L.point(200, 300));
 * ```
 *
 * Note that `Point` does not inherit from Leaflet's `Class` object,
 * which means new classes can't inherit from it, and new methods
 * can't be added to it with the `include` function.
