Well and montage images now render at their true aspect ratio instead of always being stretched into a square. Non-square tiles (for example, 4:3 images from Keyence instruments) previously got squeezed to fit a square cell, which visibly stretched round wells into ovals.
Both the stitched image output and the well page display now derive and preserve the real tile proportions, so wells display correctly regardless of the source camera's aspect ratio.
