What’s the fastest way to draw an image to the screen in JavaScript from array of RGB pixels?

I’m working on a graphics frontend that renders server-side and pushes screen updates to a browser by sending compressed images to the client (think VNC). I’ve decided the overhead of encoding PNGs is too high, so currently I’m sending raw blobs of 8-bit RGB pixel values through a websocket (with compression enabled). This is actually…
