so the new GUI sets up a canvas and picks the coordinates, and that is
fed into i.ortho.photo using the vector text format. We just need to
pass the interactive info from the new GUI to the module through a pipe
to stdin or a file= option tunnel, and recreate the info needed to setup
the GUI backdrop.
