    Description

      Using QMLSCENE_DEVICE=softwarecontext with an Image element that has an SVG source results in an image that is not smoothly filtered even when smooth is explicitly set to true.

      import QtQuick 2.1

Image {
    width: 512
    height: 512
    sourceSize.width: 64
    sourceSize.height: 64
    source: "https://dev.w3.org/SVG/tools/svgweb/samples/svg-files/aa.svg"
    smooth: true
}

      However if you set smooth to false, the image appears to be smoothly filtered:

      import QtQuick 2.1

Image {
    width: 512
    height: 512
    sourceSize.width: 64
    sourceSize.height: 64
    source: "https://dev.w3.org/SVG/tools/svgweb/samples/svg-files/aa.svg"
    smooth: false
}

      So it seems the smooth property has the opposite of the intended effect when using the 2D renderer.
