output frame should happen in the same thread as logic frame #94

from switching to ash, i just realized that using frames in flight, the cpu is not waiting for the gpu to end the drawing.

this means, with the current design, there are at least 2 frames delay between user input and displaying the frame. this can be reduced to 1 if the job were to be removed.

0 frame delay can be achieved, by not using frames in flight, however it's questionably if this is practical, as that would waste cpu cycles.

this also makes the double buffer design of god state redundant, which removes a major headache.
