Started upon a delegate protocol for the AudioQueue, resolving my use of a deprecated API while I'm at it.

Increased buffering range of audio as a quick fix for now. Basically means: increased latency as a short-term fix.

Hacked my 6522 to work. Mistake is in not returning output as input when appropriate — i.e. that I'm ignoring data direction. Also fixed K and L keys.

Actually, I'm dithering over whether the 6522 should be an ordinary class or a curiously-recurring template. But it'll need a file, definitely.

Added forwarding of a loaded PRG from the Swift document to the wrapper. So I think that possibly completes the Swift side of things?

System ROMs are now supplied to the Vic-20 wrapper, though they stop there. I also factored key forwarding out of the ElectronDocument and into the superclass, depending upon the child conforming to CSKeyboardMachine.

Reorganised system ROMs out of the Mac-specific folder, adjusted Mac code to expect to find them organised hierarchically (as how many os.roms am I going to have?) and added readme files to explain what's missing from the Git repository.

Back to asynchronous updates and drawing, to try to improve guarantees on audio latency; experimenting with whether other parts of the approach are fundamentally flawed; added a broad-phase for scheduled updates on the 2600.

With no regard to performance whatsoever, endeavoured to bring sound to the 2600. It's very scratchy, so something is wrong.

Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be.

Spotted error was in texture target all along. This now gets as far as showing something a lot like the correct display, but precision is way off. Way off.
