     ARGUMENTS
          array_size
                    Specifies the size of ink_array_return and
                    logical_array_return.  The caller must pass in
                    arrays of this size.

          font_set  Specifies the font set.

          ink_array_return
                    Returns the ink dimensions for each character.

          logical_array_return
                    Returns the logical dimensions for each character.

          num_bytes Specifies the number of bytes in the string
                    argument.

          num_chars_return
                    Returns the number of characters in the string
                    argument.

          num_wchars
                    Specifies the number of characters in the string
                    argument.

          overall_ink_return
                    Returns the overall ink extents of the entire
                    string.

          overall_logical_return
                    Returns the overall logical extents of the entire
                    string.

          string    Specifies the character string.

     DESCRIPTION
          The XmbTextPerCharExtents and XwcTextPerCharExtents
          functions return the text dimensions of each character of
          the specified text, using the fonts loaded for the specified
          font set.  Each successive element of ink_array_return and
          logical_array_return is set to the successive character's
          drawn metrics, relative to the drawing origin of the string
          and one rectangle for each character in the supplied text
          string.  The number of elements of ink_array_return and
          logical_array_return that have been set is returned to
          num_chars_return.

          Each element of ink_array_return is set to the bounding box
          of the corresponding character's drawn foreground color.
          Each element of logical_array_return is set to the bounding
          box that provides minimum spacing to other graphical
          features for the corresponding character.  Other graphical
          features should not intersect any of the
          logical_array_return rectangles.

          Note that an XRectangle represents the effective drawing
          dimensions of the character, regardless of the number of
          font glyphs that are used to draw the character or the
          direction in which the character is drawn.  If multiple
          characters map to a single character glyph, the dimensions
          of all the XRectangles of those characters are the same.

          When the XFontSet has missing charsets, metrics for each
          unavailable character are taken from the default string
          returned by XCreateFontSet so that the metrics represent the
          text as it will actually be drawn.  The behavior for an
          invalid codepoint is undefined.

          If the array_size is too small for the number of characters
          in the supplied text, the functions return zero and
          num_chars_return is set to the number of rectangles
          required.  Otherwise, the functions return a nonzero value.

          If the overall_ink_return or overall_logical_return argument
          is non-NULL, XmbTextPerCharExtents and XwcTextPerCharExtents
          return the maximum extent of the string's metrics to
          overall_ink_return or overall_logical_return, as returned by
          XmbTextExtents or XwcTextExtents.
