  * OverlayRendering: correctly scale the overlays borders and edges to
    match settings DashStyle has been modified to return smart pointers
    of textures that are loaded depending on the scale level. The cache
    will make sure that we don't duplicate the textures and that they
    get removed when not needed anymore. Also thanks to this the
    SearchBarSpinner textures (and the other spinners as well) uses the
    SVGs scaled at the proper size (I desgined a new SVG for the
    magnifier, as we only had a PNG). (LP: #1283415)
