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

Still stepping slowly towards a working composite mode, switched the RGB sampling function to returning a vec4 , which may be of benefit to any machine with a brightness part of an RGB signal, and started edging towards at least having the correct GLSL programs ready for converting composite output.

Switching momentarily back to monitor mode, resolved why I was suddenly getting no output upon creating some texture targets.

Added a note to future self, put the scan edge generator back to the way round it was before.

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.

Attempted a switch to the real PAL visible area and to something a bit like a real phosphor decay.

Fixes: now setting correct frame time estimate, properly enabling the timestamp attribute, and ensuring that the Electron flushes screen work at least once per host frame update.

Fixed output precision compared to the new approach of trusting the flywheel for position, and eliminated fixed-Acorn constants. Also re-enabled the faded previous frame, at least temporarily.

Made an attempt to switch to the flywheels for both vertical and horizontal sync, and to act more appropriately for out-of-bounds sync requests. Lots of tweaking to do, I fear.

Switched to generating an interlaced output, that apparently being correct. Enabled a poor man's version of phosphor persistence to smooth things out a little. It's not completely unconvincing.

Certainly at least seriously considering a separate holder for the "compile a shader" logic. Otherwise taking steps back towards PAL/NTSC decoding.

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.
