An icon which is loaded from SVG file can be rendered in any size and
resolutions natively. We were generating 16x16, 24x24, and 32x32
pixmaps, and not appending but creating new icon. Therefore for SVG
icons we effectively were reducing their quality.
If icon already contains 7 (or more) sizes (16 to 256 px) we do not
resize it anymore.
