Tested in NDE Neon by running `kinfocenter` with `QT_SCALE_FACTOR=1.3` and the standard Plasma logo
- 1x scale factor, low-res pixmap: no change, looks fine
- >1x scale factor, low-res pixmap: no change, looks pixellated
- 1x scale factor, vector pixmap: no change, looks fine
- >1x scale factor, which is an SVG.vector pixmap: looks great!
Before:

After:

Low-resolution icons still appear blurry and pixellated in HighDPI mode, as (sadly) expected.
