[GRASS-dev] r.sun and pj_do_proj() calls

[Seth Price]

I'm looking for when that pj_do_proj() call was added (and by whom and  
why). I'm looking for the full history of this file:
http://newtrac.osgeo.org/grass/browser/grass/trunk/raster/r.sun/rsunlib.c

I can't seem to go back far enough, though. This is the furthest I can  
get:
http://newtrac.osgeo.org/grass/browser/grass/trunk/raster/r.sun2/rsunlib.c?rev=34556

Which came from here:
http://newtrac.osgeo.org/grass/log/grass-addons/r.sun_horizon/r.sun2/rsunlib.c?rev=25783

The comments say it came from JRC, but what is that?


I do see that the original function didn't use pj_do_proj(), but I'm  
not sure why it was added:
http://newtrac.osgeo.org/grass/browser/grass/trunk/raster/r.sun/main.c?rev=38127


Does anyone know what revision pj_do_proj() was added in?
