I actually think the person meant it like he said it, but that he was meaning snapping. As in, when a house gets close enough to another house it should snap so I can build them right next to each other. Could perhaps be useful for houses, but other buildings are rarely all that useful to put right next to each other. Not sure why one would like any random (ok, not really random, but it seems like it would feel a bit random) direction, perhaps to have an area in the corners that would scroll diagonally, but apart from that I don't think it would feel all that useful, seems like one would get lost I could be wrong though, haven't played any game that does it as far as I know. I have never had any problems with this. Not that I can remember using the stylus though, only the mouse, can't see why one would use the former. Could be on Linux perhaps? Though I do remember having problems in other games, but that was when zooming, was really jumpy/spinning/weird in RTW and a few other games.
