 * Determines the bytes-per-pixel for the #CoglPixelFormat retrieved
 * from cogl_texture_get_format() and multiplies that by the texture's
 * width.
 *
 * <note>It's very unlikely that anyone would need to use this API to
 * query the internal rowstride of a #CoglTexture which can just be
 * considered an implementation detail. Actually it's not even useful
 * internally since underlying drivers are free to use a different
 * format</note>
 *
 * <note>This API is only here for backwards compatibility and
 * shouldn't be used in new code. In particular please don't be
 * mislead to pass the returned value to cogl_texture_get_data() for
 * the rowstride, since you should be passing the rowstride you desire
 * for your destination buffer not the rowstride of the source
 * texture.</note>
 *
 * Return value: The bytes-per-pixel for the current format
 *               multiplied by the texture's width
 *
 * Deprecated: 1.10: There's no replacement for the API but there's
 *                   also no known need for API either. It was just
 *                   a mistake that it was ever published.
