Switched to a more rational interface, ensured output_level will work when eventually needed, and that neither it nor output_data attempts a recursive lock.

Things are back pretty much to where they were, but offset is eliminated as an input.

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.

With a lot of logging also currently ongoing, fixed circular ranges for clearing and when covering an entire buffer.

Started on an attempt not to treat the various buffers as free to loop within, starting with the input texture.

Proven through deliberate inefficiency: the issues are (i) texture upload; and (ii) buffer wraparound.

Made attempts (i) to flush buffers before unmapping them; and (ii) to bring texture uploads within the new orthodoxy.

Factored out wraparound buffer addressing where it's otherwise going to get really repetitive; need to look at using the same approach for the glTexSubImage2D step at least but that probably means properly encapsulating the buffer builder's state.

Commented out sync; it can probably be implicit.

Attempted to simplify threading, thereby allowing machines to be constructed within a valid GL context, and started adding appropriate GL syncs. Which all oddly drops everything to a negligible FPS. Investigation will follow.

Simplified API down to their being a single texture with a specified depth.

A shortcut here and a shortcut there; this allows me at least to determine whether use of a PBO gains anything.

Made further attempts to tidy up; trying to demarcate between public interface and private.
