WebImage Resize is this behavior correct?

[MuhAspese]

So, i upload big image (2000x3000) and want to resize it, then crop and ok.As u can see here: http://i.stack.imgur.com/IWwpg.pngI have WebImage with 3000 height, 2000 width. So, resize please to 402x602, then crop back to 400x600.Result: http://i.stack.imgur.com/dB5KX.pngBut what the hell? Why i really get 401x602?!p.s. Don't have enought reputation to insert images directly in post, sry for that.
