    texthandles: set input shape on handles' window
    
    This improves both interaction and theming, as it allows
    arbitrary handle shapes while just being draggable from
    the visible areas.
    
    This way themes can set up handles with the hotspot visually
    displaced from the horizontal center, as long as the hotspot
    lies centered in the image/svg asset.
