      Description

      If you use the QtQuick Image on a device with a high-DPI scaling higher than 1, and set a size for a svg image, it will be loaded for the given size, and not the real, scaled size. Simple example:

      Image {
          anchors.centerIn: parent
          source: "https://storage.googleapis.com/material-icons/external-assets/v4/icons/svg/ic_autorenew_black_24px.svg"
      }
      

      If running on a normal display, it's fine. But on Android, for example, with the DPI-Scaling Factor 2 (automatic value), it becomes blurred, because it's loaded for 24x24 pixels, but drawn with the double resolution!
