 Pascal Convertion was made by Ido Kannner - kanerido@actcom.net.il

Thanks:
         I want to thanks to oliebol for putting up with all of the problems that was found
         while translating this code. ;)

         I want to thanks #fpc channel in freenode irc, for helping me, and to put up with my
         wierd questions ;)

         Thanks for mmc in #xlib on freenode irc And so for the channel itself for the helping me to
         understanding some of the problems I had converting this headers and pointing me to resources
         that helped translating this headers.

History:
        2004/10/15           - Fixed a bug of accessing second based records by removing "paced record" and
                               chnaged it to "reocrd" only.
        2004/10/04 - 06      - Convertion from the c header of XKBgeom.h.
        2004/10/03           - Removed the XKBstr_UNIT compiler decleration. Afther the joined files,
                                                                                     There is no need for it anymore.
                                                                             - There is a need to define (for now) XKBgeom (compiler define) in order
                                                                               to use the code of it. At this moment, I did not yet converted it to Pascal.

        2004/09/17 - 10/04   - Convertion from the c header of XKBstr.

        2004/10/03           - Joined xkbstr.pas into xkb.pas because of the circular calls problems.
                             - Added the history of xkbstr.pas above this addition.

        2004/09/17           - Fixed a wrong convertion number of XkbPerKeyBitArraySize, insted
                               of float, it's now converted into integer (as it should have been).

        2004/09/15 - 16      - Convertion from the c header of XKB.h.
