Reduce kept state in JPEG decoder
...
We don't have to keep track of this much data between rects, so
restructure things to make it more simple. This allows the JPEG parsing
code to be a pure function which only depends on the input.

Handle correct data offset in raw decoder
...
There is often buffered data ahead of the pixel data so we need to take
this in account when making sure pixels are opaque.

Handle empty rects from the server
...
These are very pointless for the server to send, but not a violation of
the protocol so we need to be able to handle them. We've seen this
happen in real world scenarios a few times.

Switch to RGBx pixel format
...
This is what the browser wants so it avoids having to spend time
converting everything. Unfortunately it usually means the server instead
needs to convert it for us, but we assume it has more power than we do.
