A bit stuck on creating a new image

[Doug Lerner]

Whew! It took forever to figure out, but I finally stumbled across the right
combination of image compression, base64 encoding and required properties
that need to be communicated over the socket and it seems to be working.

I was surprised that I was able to get this to work, though, with just the
paintCompression and imageData properties, and that that value of the image
itself was not required. That seems a bit counter-intuitive.
