Details

Because we know the panorama canvases are opaque, you should set the moz-opaque attribute on those canvases. It lets us use an RGB24 rather than ARGB32 surface, which is a significant performance benefit.

As long as you're in a privileged context (I think this matters), you can setAttribute("moz-opaque", "true") on the html <canvas> element (*not* the 2D rendering context!), and you'll transparently get the performance benefits.
