Enshrined a default colour burst amplitude. Which now everybody relies on. The 102 figure is derived from the burst apparently being 40 IRE.

Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80.

Switched the 6560 to two bytes per pixel, since one isn't sufficient for precision and because mixing up the implementation might help me to figure out what's amiss.

It turns out that the Vic has a 1.6Khz low-pass filter. So added that.

Turned the 6560 into an ordinary template, similar to the rest of the project, albeit right now with a fairly shonky internal implementation. Fixed a Mac-specific interface sizing issue.

Converted the 6560 fully into a template; worked on allowing the typer to run at a much faster rate where hardware has some trigger by which it can request the next key.

Shunted code for the main part up into the header, in advance of turning it into a template so as to bring it inside the normal orthodoxy.

Added a 'power on' flag that is set automatically at construction but can be declined. Saves all that stuff of every machine having to set and then unset the RST line, and fixes an Electron bug related to that.

It appears the Vic's output is sine-ish, after all. Also adjusted centre of display, simultaneously adding some validation on that.
