Rendering of scaled SVG resources in QML shows a degraded quality.
I created some SVG images on my own with Inkscape.
As long as they stay 1:1 they look OK in QML. When they are scaled, they seem to loose every vectorial property they have. Seems like the 1:1 image is scaled as if it was a bitmap.
This results in a bad looking aliasing effect.
See attached files.
dimmer-back.svg: the test SVG file
SVGTest.qml: can be tested with qmlscene

scaling_ok.png: the screenshot of the KDE preview. Any other software scales the SVG file OK (Gwenview, Gimp, etc..)
