35 * @param[in] textureManager The texture manager
36 * @param[in] size The width and height to fit the loaded image to.
37 * @param[in] fittingMode The FittingMode of the resource to load
38 * @param[in] samplingMode The SamplingMode of the resource to load
39 * @param[in] urlList List of urls to cache
40 * @param[in] maskingData Masking data to be applied.
41 * @param[in] observer FrameReady observer
42 * @param[in] batchSize The size of a batch to load
43 * @param[in] interval Time interval between each frame
44 * @param[in] preMultiplyOnLoad The flag if image's color should be multiplied by it's alpha
46 * This will start loading textures immediately, according to the
47 * batch and cache sizes. The cache is as large as the number of urls.
