+ * @brief Flush all caches.
+ *
+ * Frees all data that was in cache and is not currently being used to reduce
+ * memory usage. This frees Edje's, Evas' and Eet's cache. This is equivalent
+ * to calling all of the following functions:
+ * @li edje_file_cache_flush()
+ * @li edje_collection_cache_flush()
+ * @li eet_clearcache()
+ * @li evas_image_cache_flush()
+ * @li evas_font_cache_flush()
+ * @li evas_render_dump()
+ * @note Evas caches are flushed for every canvas associated with a window.
