Implemented seeking on tapes, mucked about a bit more with the Commodore analyser, at least temporarily removed cropping from the Vic emulator.

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

Ensured the 6560 knows its real audio clock on a PAL machine; removed some stray semicolons.

Collapsed 6560 template to a more direct loop, albeit with quite a bit still left to fix.

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.

Fixed 6560 addressing error, added an autotyper for Vic disks (more work potentially needed), fixed semantics for testing whether a 6502 is about to reset.

Demonstrated that issue is coloured borders, made a guess as to buffer exhaustion, upped limits as a temporary fix.

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.

Made an attempt to adjust the 6560 to a model compatible with that advocated by the available documentation. Exact decision timing may need further work.

Made some minor documentation improvements, killed 6522.cpp as the 6522 is going to be a template only, attempting to promote good inlining behaviour.

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

Experimented with table-based GLSL lookups, and a sine curve. Now _exceedingly_ slow, but colours are correct if I pretend I'm in the YUV colour space.
