There is a specific event for when an image has finished loading,
so trigger on that rather than polling. The polling interval of
requestAnimationFrame() can also be very large.
The callers don't need to concern themselves with how images are
rendered, so hide the details behind the API. This also avoids
exposing the render queue.
This commits prevents Util from modifying the window object.
- `window.requestAnimFrame` was removed (no polyfill is needed anymore)
- the potential redefinition of `console.log` and friends was removed
(all supported browsers have `console.xyz` defined anyway)
This commit restructures noVNC, splitting it into the core directory
and the app directory, with the former containing core noVNC parts,
and the latter containing parts specific to the application.
