//
//	1. Enforce API surface and semantic compatibility with 1.9.x branch
//	2. Improve the module's maintainability by reducing the storage
//		paths to a single mechanism.
//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)
//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

    /**
     * SVGInject
     *
     * Injects the SVG specified in the `src` attribute of the specified `img` element or array of `img`
     * elements. Returns a Promise object which resolves if all passed in `img` elements have either been
     * injected or failed to inject (Only if a global Promise object is available like in all modern browsers
     * or through a polyfill).
     *
     * Options:
     * useCache: If set to `true` the SVG will be cached using the absolute URL. Default value is `true`.
     * copyAttributes: If set to `true` the attributes will be copied from `img` to `svg`. Dfault value
     *     is `true.
     * makeIdsUnique: If set to `true` the id of elements in the `<defs>` element that can be references by
     *     property values (for example 'clipPath') are made unique by appending "--inject-X", where X is a
     *     running number which increases with each injection. This is done to avoid duplicate ids in the DOM.
     * beforeLoad: Hook before SVG is loaded. The `img` element is passed as a parameter. If the hook returns
     *     a string it is used as the URL instead of the `img` element's `src` attribute.
     * afterLoad: Hook after SVG is loaded. The loaded `svg` element and `svg` string are passed as a
     *     parameters. If caching is active this hook will only get called once for injected SVGs with the
     *     same absolute path. Changes to the `svg` element in this hook will be applied to all injected SVGs
     *     with the same absolute path. It's also possible to return an `svg` string or `svg` element which
     *     will then be used for the injection.
     * beforeInject: Hook before SVG is injected. The `img` and `svg` elements are passed as parameters. If
     *     any html element is returned it gets injected instead of applying the default SVG injection.
     * afterInject: Hook after SVG is injected. The `img` and `svg` elements are passed as parameters.
     * onAllFinish: Hook after all `img` elements passed to an SVGInject() call have either been injected or
     *     failed to inject.
     * onFail: Hook after injection fails. The `img` element and a `status` string are passed as an parameter.
     *     The `status` can be either `'SVG_NOT_SUPPORTED'` (the browser does not support SVG),
     *     `'SVG_INVALID'` (the SVG is not in a valid format) or `'LOAD_FAILED'` (loading of the SVG failed).
     *
     * @param {HTMLImageElement} img - an img element or an array of img elements
     * @param {Object} [options] - optional parameter with [options](#options) for this injection.
