When cursor position or editor text changes many input method query attributes like
cursor rectangle, cursor position, surrounding text, current selection and anchor
position change as well. Checking in text control and editor classes what of those
related attributes have exactly changed before calling the update increases code
complexity unnecessarily for a little benefit. Qt::InputMethodQueries flag can still
be used to optimize more independent cases when attributes change individually, which is
more common for input methods hints, fonts, platform data, maximum length or enabled
attributes.
