revision 0.6
date: 1999/02/02 17:18:45;  author: corliss;  state: Exp;  lines: +166 -53
--Fixed the small problem of the text fields not liking 0s. (Whoops!)
  Never put the the getch sequence as the test for the while loop. :-P
--Fixed the cursor location bug, as well as the paging bug.
--Expanded support for all printable characters on the PC keyboard in
  text fields.
--Fixed the cursor/line bug when the cursor position is on the last line,
  and on a new line character in the text field widget.
--Added Up/Down arrows to indicate existing content out of view in the
  window in the text field widget.
--Added Up/Down arrow, Page Up, Page Down support to the text field widget.
--Moved the $colour scalar into the BEGIN tag clause, so the has_colors()
  function need only be called once.
--Moved conditional declaration of the select_colours function into the
  function itself, dependent upon the persistent $colour.
--select_colours now returns a 1 if it could successfully set the colour,
  as per $colour, and a 0 if not.
--init_colours() *must* be called now, since this is the routine that sets
  the value of $colour, and the colour pairs.
--Each widget now draws its border with A_BOLD if the $colour is not
  available and 'draw_only' was not set.
--Added Up/Down arrows to indicate list entries that exist out of view of
  the window in the list box.

--All widgets now handle their own special keys
--Text widget now handles modification to content as well, returning the
  the updated content to the calling routine.
--cal output now stored in a persistent array, so it only needs to be
  called when moving to a new month, now.
--None of the widgets need to have window declared for them, now.  All
  of them will create their own derived windows, and destroy them upon
  exiting the routine.
--Replaced all chr calls in box commands with the ACS_* constants, for
  more reliable rendering on various term types.
--New select_colour function for selecting character colour by name.  Only
  supports red, blue, green, and yellow, currently.
