- * Loads an image with progress callback.
- *
- * The `onprogress` callback will be called by XMLHttpRequest's onprogress
- * event, and will receive the loading progress ratio as an whole number.
- * However, if it's not possible to compute the progress ratio, `onprogress`
- * will be called only once passing -1 as progress value. This is useful to,
- * for example, change the progress animation to an undefined animation.
- *
- * @param  {string}   imageUrl   The image to load
- * @param  {Function} onprogress
- * @return {Promise}
