* Description:  Provides definitions of the tags for TIFF, EXIF, Interoperability,
*               GPS, Meta, Kodak Special Effects and Kodak Borders IFD's.
*
* Author:       Evan Hunter
*
* Date:         1/8/2004
*
* Project:      PHP JPEG Metadata Toolkit
*
* Revision:     1.11
*
* Changes:      1.00 -> 1.11 : Added TIFF compression types ZIP, LZW and JPEG
*                              Added embedded XMP tag
*                              Added embedded Photoshop IRB tag
*                              Fixed GPS tags after testing
