The main diffraction QGraphicsView enabled SmoothPixmapTransform, which
bilinearly resamples the full detector pixmap on every repaint. For a
pixel-detector image nearest-neighbour is both cheaper and preferable
(pixels stay crisp when zoomed in instead of blurring), and it removes a
per-repaint resampling cost that is felt most over remote X forwarding,
where every repaint ships rasterised pixels over the wire.
