These functions appear correctly to model the NTSC and PAL palettes; the CRT's attempt to switch function doesn't work properly yet though.

Started on an attempt not to treat the various buffers as free to loop within, starting with the input texture.

Oh, of course, it's that the output vertex array doesn't get initialised unless there's an RGB shader program. Silly oversight. Fixed. And switched back to TV output for correct colours.

Added a dump-the-input default RGB output shader. Which at least proves that the Atari 2600 is generally still working.

Made an attempt to reestablish the Atari 2600 output connection despite various changes (TODO: generalise that stuff), and to start creating the composite shader.

With the provision of an extra hint to the CRT and, finally, the realisation about why my scans weren't exactly joining up, improved output precision.

Onward with carrying this through to the bitter end, this at least results in all the appropriate knowledge and call-ins occuring at the CRT.

Got a bit higher level in CRT timing specification. Which internally allows it now to infer the colour clock frequency. Which will be helpful momentarily.

Set about documenting the CRT; while doing so decided to add an optional clock divider for input; having done so decided to try to exploit it with the Electron.

Added a lot of commenting to the CPU6502 definition, simplifying its construction. Added missing nullability modifier to CSElectron. Fixed bad-habit Objective-C style naming on the Electron's Interrupt enum.

Started working on a shell for the Electron emulation, including factoring out the common CRT delegate -> Objective-C bridging, serial dispatch queue and frameskipping logic from the Atari 2600 shell.
