wxGUI GCP Manager for photo to image registration

DESCRIPTION
7       This module is based on g.gui.gcp, the GCP manager of GRASS GIS.  It is
8       part of i.ortho.photo suite.
9
10       The aim of this module is to give absolute location values to the fidu‐
11       cial points present (in number of 4 or 8) in a scanned aerial photo.
12
13       This  is  necessary  as (manual) scanning introduces distortions, rota‐
14       tions and also may not be limited to scan the boundary of the photo it‐
15       self.  It  is thus necessary to give to each fiducial the exact coordi‐
16       nates in mm as given by  the  aerial  photographic  instrument  design,
17       which is unique per camera.
18
19       This  module  requires  you to have made a group with your aerial photo
20       (i.group), a camera description file (i.ortho.target) and use  them  to
21       launch  the module. Additional requirements are the order of rectifica‐
22       tion (1 if no of Fiducials is 4, 2 if no of Fiducials is 8) and an  ex‐
23       tension file (if not given, defaults to \$filename_ip2i_out)
