    Heal: Make HealTool work when brush is partially outside of layer
    
    Fix for bug 568098 https://bugzilla.gnome.org/show_bug.cgi?id=568098
    Removes condition for not applying heal when (destination)brush is partially outside of layer.
    Instead heal is not applied when brush is completely outside.
