Made a decision to clean up by creating per-shader classes. Well, more or less. First thing to be factored out: the output shader.

Ensured the GL context is available when switching Atari 2600 output, and that it locks the output.

Oh, of course, I can use GL_CONSTANT_ALPHA so that new colours can be painted at alpha 1.0 while possibly saturating with old colours.

Reintroduced the CRT delegate and the 2600's automatic region switching. Albeit that the CRT itself doesn't adjust properly to new timings yet.

Oh, of course, it's that the output vertex array doesn't get initialised unless there's an RGB shader program. Silly oversight. Fixed. And switched back to TV output for correct colours.

Added a dump-the-input default RGB output shader. Which at least proves that the Atari 2600 is generally still working.
