How do I determine the current width of a XmText widget in terms of
character spaces?  For example, if my XmText widget is inside a form and
the form is resized, I want to know how many characters are actually
being displayed.  The XmNcolumns resource is only the initial width,
right?  Also, how can I can determine what is currently displayed in the
text widget?  Note that this is different from the value inside the text
widget because of scrolling (even in single_line_edit mode) or resizing.
For example, if I have a 100 character string in my text widget and
only 10 characters are visible at a time, how do I find out which 10 are
being displayed?  I even looked at some of the fields in the internal
XmText structures but I didn't find the appropriate ones.
