Introduces formal setting of the output volume to SampleSource.
...
Previously every output device was making its own decision. Which is increasingly less sustainable due to the CompoundSource.

Attempts to get as far as running the MultiMachine.

In doing so, fixes the long-standing bug that machines that output audio but don't have a listener produce a divide by zero.

Corrects calculation of intermediate buffer width multiplier.
...
Specifically: I had failed to factor in that the multiplied-up input frequency might be less than than the full width of the bitmap.
The Atari and MSX in particular now look much better.

"Doubles" the bandwidth given to composite signals.
...
Because I suspect it may inadvertently have been halved previously. I'm investigating.
