(repost - got lost somewhere the first time) I stumbled upon this link describing the use of the Diagonal (45 degree diagonal from each corner of an image) as the optimum crop guide ("better" than rule-of-thirds or golden rule).
http://www.diagonaalmethode.nl/ I hacked together a patch to add the Diagonal crop guide. So, should I open an enhancement bugzilla and include the patch? My patch isn't perfect - hence posting here since it requires some discussion. If the crop box is a portrait, then it works, if landscape (X > Y) then the guides extend beyond the crop rectangle. I don't know how to fix this cleanly (using an if statement doesn't seem efficient). Any guidance (on or off list) would be appreciated.
