Increased buffering range of audio as a quick fix for now. Basically means: increased latency as a short-term fix.

It appears the Vic's output is sine-ish, after all. Also adjusted centre of display, simultaneously adding some validation on that.

Experimented with table-based GLSL lookups, and a sine curve. Now _exceedingly_ slow, but colours are correct if I pretend I'm in the YUV colour space.

Hacked my 6522 to work. Mistake is in not returning output as input when appropriate — i.e. that I'm ignoring data direction. Also fixed K and L keys.
