With a panel table, the viewer and the broker preview gather the stored image
onto the detector plane (AssembleToPlane) and draw on that: spots,
predictions, rings, beam centre and ROIs are plane coordinates, so they now
land on the right pixels for a stored (stacked or moved-module) layout, where
they were drawn as image pixels before. The viewer scene is the plane; its
image item sits at the raster's origin (JFJochImage::origin_, zero for a flat
detector). Mouse readout, pixel labels and the magnifier read the shown
raster; top pixels and saturation crosses are mapped from the stored pixel to
the plane; an ROI turned into a user mask is tested per stored pixel at its
plane position.
A flat detector (empty table) takes the old path verbatim: the shown pixels
alias the image, origin (0, 0) - a JF/EIGER file renders identically.
common/AssembleToPlane.h is a TEMPORARY header-only version so this stage
builds on its own; stage 3 owns the file and its version replaces this one at
merge (callers use AssembleToPlane(modules, image, width, height,
PlaneBounds, gap) -> PlaneRaster{x0, y0, width, height, pixels}).
Test: PreviewImage_PanelLayout.
