 *  Dataset Filters
 *
 *      This is a filter, similar to the H5Z* filters. However, these
 *      transformations are applied to the data before a write or after a
 *      read.
 *
 *          - If applied before a write, a permanent change of the data
 *            may take place.
 *          - If applied after a read, the data is only changed
 *            in memory.
 *
 *      The transformations are transitory (not saved with the dataset).
 *      The transformations aren't automatically reversible, since this
 *      isn't possible in all cases and not possible if the original
 *      transformation was lost (it being transitory).
