[PROJ] Minor bug in src/apps/cct.cpp

[Houder]

Hi,

It would be nice if this minor bug in src/apps/cct.cpp could be 
repaired.

I noticed a (to me irritating) difference in the output of the cct 
command
when an "angular" unit is printed.
Angular? Radian or degree.

A width of 14 is used when printing radians and a width of 13 is used 
when
printing degrees.

Looking around, I found the bug in cct.cpp around line 390 ...

Here is the code:

if "radians"[1] { // what about degrees?
   proj_todeg // convert to degrees (cct is supposed to output degrees)
   print %14.*f decimals_angles, degrees // decimals_angles = 10 by 
default
} else // meters etc. ... Well, that is the intention, but ...
   print %13.*f decimals_distances, meters // decimals_distances = 4 by 
default
--
[1] proj_angular_output (i.e. should really be called 
proj_radian_output)

Before v7, proj_degree_output() did not exist; but now it does, cct.cpp 
can
be modified (repaired) as follows:

if "radians"[1] OR "degrees"[2] { // i.e. not meters etc. ...
   if "radians"
     proj_todeg // convert to degrees (cct is supposed to output degrees)
   print %14.*f decimals_angles, degrees // decimals_angles = 10 by 
default
} else // meters etc. !
   print %13.*f decimals_distances, meters // decimals_distances = 4 by 
default
--
[1] proj_angular_output
[2] proj_degree_output

The above has been verified against v7.2.0

Here is the real code:

         /* Time to print the result */
         // Note: proj_angular_output() should be called 
proj_radian_output()
         if (proj_angular_output (P, direction)
            || proj_degree_output (P, direction)) {
             if (proj_angular_output (P, direction)) {
                 point.lpzt.lam = proj_todeg (point.lpzt.lam);
                 point.lpzt.phi = proj_todeg (point.lpzt.phi);
             }
             print (PJ_LOG_NONE, "%14.*f  %14.*f  %12.*f  %12.4f%s%s",
                    decimals_angles, point.xyzt.x,
                    decimals_angles, point.xyzt.y,
                    decimals_distances, point.xyzt.z,
                    point.xyzt.t, comment_delimiter, comment
             );
         }
         else
             print (PJ_LOG_NONE, "%13.*f  %13.*f  %12.*f  %12.4f%s%s",
                    decimals_distances, point.xyzt.x,
                    decimals_distances, point.xyzt.y,
                    decimals_distances, point.xyzt.z,
                    point.xyzt.t, comment_delimiter, comment
             );
     }
