A dockable strip of thumbnails for a handful of representative images, with
spots overlaid so a real pattern reads like a constellation; click opens that
image.
- JFJochViewerImageStrip: mode selector (evenly spaced / most spots / indexed,
computed from the dataset's per-image metrics) + a Spots toggle; a scrollable
row of thumbnail buttons; click emits imageSelected.
- The reading worker renders thumbnails off-thread and non-disruptively: load
each image via its reader, downsample by block-maximum (keeps Bragg spots),
map through the colour-scale LUT, optionally paint spots (coral indexed /
teal not), and emit thumbnailReady(image_number, QImage). File mode only.
- Docked in the bottom area, shown in the Processing perspective; the colour map
follows the display toolbar.
