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.

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.
