Comment (by afercia):

 It was suggested to use `type="number"` for the input fields, it would
 probably be a good thing even if not all browsers prevent to type non-
 numerical characters in those fields. By the way, worth mentioning the
 `onkeypress` event in `imageEdit.init()` currently triggers a function
 that doesn't allow to use the arrow keys on those fields when using
 Firefox. Worth reminding `onkeypress` works differently in different
 browsers and in Firefox it fires when using the arrow keys so the fields
 will be blurred because of:

 {{{
 if ( 36 < k && k < 41 ) {
         $(this).blur();
 }
 }}}
 Thinking this part and all the events in the Image Editor should be
 completely reviewed, not sure if in this ticket.
