Auto Deskew

[quantum]

There is image->rotate->auto de-skew in the full program. Why can't we do this in NConvert?

Is there any chance of including it in the next update?

Also, if it is in NConvert, it would be nice to have a parameter to control it. ImageMagick has the threshold parameter:

Although I admit I'm not sure what that parameter actually does.
