Coordinate Canvas

A pan/zoom viewport with content-space coordinate mapping. A marker lives at fixed content coordinates; focus the viewport and press `+`/`-` to zoom or the arrow keys to pan. The marker's content coordinate never changes while its rendered size scales with the zoom and its rendered position translates with the pan.
