d97a073d1b Adds the necessary routine for all machines to be able to respond to get_scan_status. 
They all just as the CRT, as all are currently based on the CRT. Which doesn't currently know the total clock rate it would need to in order properly to scale the answer to the question. Further thought coming.

4de121142b Adds a flags parameter to the BestEffortUpdater delegate. 
On the Cocoa side, cuts Swift out of the update loop, as that seems merely to add code.

cb61e84868 Starts building out higher-level run_until functionality. 
Specifically: you can now run until the next set of speaker samples has been delivered.

8349005c4b Adds CRTMachine::run_until, which will run until a condition is true. 
I want to get to being able to say "run until the beam is 60% of the way down", "run until a new packet of audio has been delivered", etc.

5391a699a4 Adds the ability for a PCMSegment to maintain 'fuzzy' (i.e. random) bits. Implements an LFSR for bit generation. 
I'm not necessarily happy with the idea of just shoving in a [pseudo-]random number generator in rather than emulating the proper process underneath, but for now I throw my arms up.
