Fence sync tied up. Remaining glitches are likely off-by-one-type errors but we'll see.

Switched back to normal frame drawing logic and cleaned up the circular range stuff a little, to make it clear that no errors lie there.

Actually, that should probably be 1/outputTextureSize, as the output range is -1 to +1.

Withdrew the pixel unpack buffer in order to avoid the potential for a paused machine to be undrawable. The cost is at least an extra memcpy per frame; I'm letting the driver worry about the whole process for now.

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.
