Hello, I am working on this bug and I have a few questions:
1. Where can I see a usage of Kipiplugins::kppreviwimage?
2. From what I've seen, when zooming in/out KPPreviewimage::slotZoomIn() uses a
constant 1.5 zoom factor. Here the zoom factor is determined by a QSlider.
Would it be ok to actually modify the ImageDisplay class rather than using
kppreviewimage?
