WMLABT - plots weather map regional temperatures labels (like 90s, 80s, etc.)

       To  use WMLABT or c_wmlabt, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in
       that order.

       #include <ncarg/gks.h>

       void c_wmlabt(float x, float y, char *label, int ipos)

       X           (Real,  Input) - An X coordinate (specified in world coordinates) of a point that specifies a
                   position for the label in LABEL.

       Y           (Real, Input) - A Y coordinate (specified in world coordinates) of a point that  specifies  a
                   position for the label in LABEL.

       LABEL       (Character, Input) - A character variable that contains the desired label.

       IPOS        (Integer,  Input) - A flag for controlling whether an optional arrow is drawn.  If IPOS is 0,
                   then no arrow is drawn and the label is centered at (X,Y).  If  IPOS  is  between  1  and  12
                   (inclusive),  then  an  arrow  is  drawn  in  one of twelve positions and (X,Y) specifies the
                   location of the tip of the arrow.

       CALL WMLABT (X, Y, LABEL, IPOS)

       Set the values for the appropriate internal parameters before  calling  WMLABT  to  produce  the  desired
       label.   The  internal  parameters that control the appearance of the labels are: RBS, RFC, RLS, ROS, and
       THT.  The appearance of the optional arrows is controlled by the internal parameters  controlling  arrows
       (see the documentation for WMLABS).
