Wherever they feel like. I got it working between viewing the pdf with pdf.js, toggling pages with a dropdown, and drawing on a canvas. When they change pages, it saves the canvas to a dataURL and builds a new pdf with jsPDF, then reloads that in pdf.js on a canvas to view it. It's a mess, really.
Also, not possible to do this server side like @derp suggested. It's just not an option with Siebel.
