 V 1.16: 02/02/99
         added WMGetDlgCode to avoid problems with shortcut-controls on the form
         changed the property name ReadOnly to ReadOnlyFile ( to avoid confusion, sorry )
         fixed updating when the font gets changed
         added OnKeyPress-support ( now you can modify the key before THexEditor will parse it 
	  in this event )
         property WantTabs : Boolean ; if true, than you can navigate between char and hex 
	  field with the TAB key, if not, you can navigate between your form's controls with 
	  the TAB key, to change the current field in THexEditor, you have to use CTRL+T.
         property ReadOnlyView : Boolean ; if true, than the text/data in THexEditor can't get
         edited via key presses, just selection , moving and scrolling are still available

 V 1.15: 01/03/99
         added option odOctal to TOffsetDisplayStyle to display line offset in 
         octal system ("8"-based)
         fixed a problem on creating a THexEditor dynamically ( thanks to John Shailes , 
	  JohnShailes@email.msn.com )
         property AllowInsertMode : Boolean ; if this is set to true, THexEditor doesn't 
	  overwrite but insert values at the current cursor position ( this cannot be set if 
         NoSizeChange is True )
         property IsInsertMode : Boolean ; readonly, if it returns true, the current mode is
         inserting (see above )
         property AutoCaretMode : Boolean ; if true, the caret will be set to a block
         in overwrite mode and to a left line in insert mode automatically

 V 1.14: not released
         fixed some bugs
         added currently unsupported variable line lengths
         added NoSizeChange property

 V 1.13: 11/07/98
         added AsText and AsHex property ( and converting functions for "aa00bb" style hex
         files ) , MaskWhiteSpaces property to avoid the '.' if you have a font that can
         display chars from #0 to #31; also typing capitals rather than lowercase chars in
         the char field is now possible ( most of this stuff has been suggested from
         Philippe Chessa , Philippe_Chessa@compuserve.com, thanks )

 V 1.12: 10/25/98
	  added Half Byte (Nibble) support (insert/delete, swap hi/lo nibbles in hex view)
	  better performance
         the markers are now available for reading/writing
	  added support for some different code types in the char view :
         ANSI , 8 Bit ASCII ( OEM / Dos style ) , 7 Bit ASCII , Macintosh(TM) character set , 
         IBM(TM) EBCDIC cp 038 also conversion of the file's contents (or a range of them) 
         from one to another code type is possible (many thanks to Christophe LE CORFEC, 
         CLC@khalif.com for ebcdic and half byte suggestions)
