Issues appear to be around timing generally. Working on it.

The penny has finally dropped that I can drive the CPU stuff in a manner completely decoupled from the GPU stuff. For much improved parallelisation.

Fixes: drop any processing backlog, try not to allow an Electron document to close mid-draw, perform a frame grab even if the emulated machine is over-processing, really really don't create a CRT until it's safe.

Attempted to simplify threading, thereby allowing machines to be constructed within a valid GL context, and started adding appropriate GL syncs. Which all oddly drops everything to a negligible FPS. Investigation will follow.

Renamed CSCathodeRayView to CSOpenGLView as it no longer has any CRT-related responsibilities. It just does the GL and manages a serial dispatch queue.

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.

Made an attempt to be more rigorous in display generation on the Electron, to make sure I deal with mid-line changes to/from blank line mode. Even if it turns out that they generate pixels.

Started making first moves towards stripping CSCathodeRayView of its responsibilities. If that can be merely an OpenGL view that presents things, things will be a lot more portable.

Added the option for the CSCathodeRayView to show only a subsection of the full scan area. Zoomed in a little on the 2600. Put in enough piping to give the Electron sight of its ROMs at least.

Okay, so this is the absolute bare minimum about of refactoring and wiring necessary to get the [unimplemented] Electron machine pumping.
