/**
 * Dataspace Definitions
 * ======================
 *
 * Dataspace is the definition of how pixel values should be interpreted.
 *
 * For many formats, this is the colorspace of the image data, which includes
 * primaries (including white point) and the transfer characteristic function,
 * which describes both gamma curve and numeric range (within the bit depth).
 *
 * Other dataspaces include depth measurement data from a depth camera.
 *
 * A dataspace is comprised of a number of fields.
 *
 * Version
 * --------
 * The top 2 bits represent the revision of the field specification. This is
 * currently always 0.
 *
 *
 * bits    31-30 29                      -                          0
 *        +-----+----------------------------------------------------+
 * fields | Rev |            Revision specific fields                |
 *        +-----+----------------------------------------------------+
 *
 * Field layout for version = 0:
 * ----------------------------
 *
 * A dataspace is comprised of the following fields:
 *      Standard
 *      Transfer function
 *      Range
 *
 * bits    31-30 29-27 26 -  22 21 -  16 15             -           0
 *        +-----+-----+--------+--------+----------------------------+
 * fields |  0  |Range|Transfer|Standard|    Legacy and custom       |
 *        +-----+-----+--------+--------+----------------------------+
 *          VV    RRR   TTTTT    SSSSSS    LLLLLLLL       LLLLLLLL
 *
 * If range, transfer and standard fields are all 0 (e.g. top 16 bits are
 * all zeroes), the bottom 16 bits contain either a legacy dataspace value,
 * or a custom value.

     *       confidence. The mapping to a linear float confidence value between

     *         float confidence = (((depthSample >> 13) - 1) & 0x7) / 7.0f;
