 * @param resizeable true in case the texture shall be loaded with advanced
 *            rescaling methods, that are more calculation intensive but
 *            look better then the normal ones
 * @param allowCompression true if the texture is compressed at default
 *            settings, false if not. Best disallow compression for static
