#3574: r.horizon: support start, stop parameters with mode 1

     Type:  enhancement  |     Status:  new
 Priority:  normal       |  Milestone:  7.4.1

 Platform:  Unspecified  |
-------------------------+-------------------------
 I'm a little bit confused on this subject, because I don't know if it's a
 bug or an enhancement.

 The documentation says "he module has two different modes of operation: 1.
 Computes the entire horizon around a single point whose coordinates are
 given with the 'coord' option." so the heights are calculated at 360.

 Why is it not possible to use the start and stop parameters for this mode?
 (unless it's a bug, but I doubt it?)

 my example (using ASTER dem):

 {{{
 r.horizon elevation=ASTGTM2_S30W071_dem
 coordinates=-70.32860418838112,-29.710728777225366 step=5 start=90 end=100
 -d
 }}}
 could return only

 {{{
 90.000000,3.942604
 95.000000,3.697479
 }}}

 Thanks.
