v0.60.1

Image trace, take two: crop and contrast. A draggable rectangle on the preview isolates one object before tracing, so you can lift a single shape out of a busy photo. Quantisation now runs in CIELAB (perceptual) with distance-based seeding, so a low colour count separates dark from light - at 2 colours the subject pops out instead of turning into grey mush, even when the background has several light tones. The crop region is quantised on its own to sharpen contrast further.
