Compare and Reference drew each pane from a whole-frame render of at most
2560 px, so 1:1 was a magnified preview and focus could not be checked.
Each pane now also renders the window on screen from the photo's own
pixels (Slot::CompareRegion), as the loupe does (#323). The media cache
keeps up to two full-size originals while either view is open, so one
pane's window does not evict the other's source.
