 * This version of the header file corresponds to the profile
 * specification version 3.4.
 *
 * All header file entries are pre-fixed with "ic" to help
 * avoid name space collisions. Signatures are pre-fixed with
 * icSig.
 *
 * The structures defined in this header file were created to
 * represent a description of an ICC profile on disk. Rather
 * than use pointers a technique is used where a single byte array
 * was placed at the end of each structure. This allows us in "C"
 * to extend the structure by allocating more data than is needed
 * to account for variable length structures.
 *
 * This also ensures that data following is allocated
 * contiguously and makes it easier to write and read data from
 * the file.
 *
 * For example to allocate space for a 256 count length UCR
 * and BG array, and fill the allocated data.  Note strlen + 1
 * to remember NULL terminator.
