Date: Fri, 13 Dec 2019 13:10:23 +0000 (UTC)
commit e55dd716e24a0e7cf8cdf768117108ecdc080e30
Author: Umang Jain <mailumangjain gmail com>
Date:   Wed Dec 11 00:35:10 2019 +0530

    StPasswordEntry: Add the peek-password-icon for show/hide passwords
    
    Also introduce a "show-peek-icon" property to enable/disable
    the peek-password-icon in the password entry. This is useful
    in cases where the peeking the password functionality needs
    to be avoided.
