There are 3 Street View modes:

   1. 'html4' - This uses simple <img> tags with no perspective warping. It
   is fast in all browsers.
   2. 'html5' - This uses Canvas 2D with perspective warping. Canvas 2D is
   software rendered so it has a low framerate.
   3. 'webgl' - This uses WebGL. WebGL is hardware rendered so it has a high
   framerate.

We pick the mode automatically based on the browser capabilities. You can
override the default mode using the experimental 'mode' option, like:
    myPano.set('mode', 'webgl');  // or 'html5' or 'html4'

WebGL is live in Chrome 9, but it is disabled in the Maps API for now as it
crashes some older machines. WebGL is in Firefox 4 and the Safari nightly
builds, so it looks like Firefox and Safari will soon support WebGL. I don't
know when WebGL will be added to mobile Safari (on the iPad).
