//          Application specific data
//
//  We use here the same concept that is used in WINSOCK 1.1 specifications.
//  All the data that come from the ColorProfile are in "network" format,
//   and we deal with that data using "host" format. The "host" byte order can
//   be either big- or little-endian, the size of the integers and floats
//   may vary too, we only require that all "host" type data must have
//   the precision  equal or higher of the "network" data.
//  The platfornm-specific implementation must provide macros or functions
//   to convert from  "network" to "host" representation.
//  Currently we do not write data into profile, so no conversion
//   from "host" to "network" is  required.
//
//  The basic types that should be defined to work with ColorProfiles are:
//
//      BOOL    -   any size variable that can hold either TRUE or FALSE
//      BYTES   -   exactly 8-bit 
//      SINT    -   signed int capable of holding at least 32 bits
//      SFLOAT  -   signed float capable of holding at least 32 bits
//      CSIG    -   entity that can hold at least 32 bits of signature
//                      in host format
//      ATTRIB  -   entity that can hold at least 64 bits of attributes
//                      in host format
//      MEMPTR  -   Pointer to the memory block which can refernce more
//                      than 64K of BYTES
//
