And actually use this functionality on MWBlockImage to highlight centred images correctly. FocusableNode * Actually use $focusable to render the highlight correctly ProtectedNode * Allow a $phantomable element to define which element to highlight on mouseenter * As phatoms are built off shields, make sure a shield is given to $phantomable RelocatableNode * Allow a $relocatable element to define which element the relocatable marker is measured against ui.Context * Use $focusable (when available) for positioning the popup Plus some documentation fixes Change-Id: I370337239af4fc935cd86757b3ce03011bae5ba8
