Well I simplified my hack for square thumbs..
added the option for portrait images to be cropped center or top
And added the thumbnail sharpener..
it only supports gd2.. but as the stuff is also imagemagick built in.. i think it should not be difficult to add imagemagick support.. feel free to add that..(i do not have imagemagick installed)
here it is.. 4 file edits.. and one extra file..
