I doubt you're going to get any satisfactory results for pixel painting directly out of the browser. Using SVG or maybe HTML5 methods may get the results you're looking for but you will be limiting your audience to advanced browsers and higher powered computers. Using a server side approach with an image overlay is by far the better choice and one that works with current browsers and even lower powered computers and connections.
