Turns a chart drawn on a canvas into pins.
A canvas has no shapes to trace, only colours, so this does what the SVG path does by other means: each pin looks at the patch of picture it stands over, decides whether anything is drawn there, and is raised where a drawn thing meets something else -- the page behind it, or a mark of a clearly different colour. Marks come out as outlines, the way the SVG path draws every mark but the focused one, so a hand can trace a bar's edges rather than meet a solid plateau.
