[Bug 11172] wouldn't it be better to return the context handler instead of void, making "context.moveTo(x1,y1).lineTo(x2,y2).lineTo..." possible and easier?

This is nice in jQuery because it sometimes lets you avoid naming extra
variables, e.g. (actual code sample I was just looking at)

  $("body").append("<script></script>").attr("src", foo);

rather than

  var script = document.createElement("script");
  script.src = foo;

which is necessary when using DOM methods because "script.src = foo" and the
equivalent setAttribute() call don't return the element they're operating on,
so you need an explicit temporary variable.  But almost any real-world canvas
use is going to want to keep around a context handler anyway, so it doesn't
look like there's any gain here.  (Although I don't see the harm either.)
