 *  always EVD_Version and the data value is the version
 *  of the file (currently 2).
 *
 *  The rest of the tags are in random order. The taglist
 *  is terminated like normally with TAG_END.
 *
 *  If there's an indication that the data value is a pointer
 *  then it's an offset relative to the start of the preferences
 *  file. Normally this kind of data like the palettes are stored
 *  after the taglist.
