2020-10-28	Fix unnecessary threaded rendering frame drops	Justin Weiss
	When DMA requests force a background queue flush, the update lace handler can no longer know there was a pending frame. If this happens often enough, it can delay the next frame indefinitely. Whenever the background queue is emptied, the next update_lace needs to force a render.

2020-10-22	Add a threaded renderer	Justin Weiss
	This change adds a gpulib implementation that accepts GPU commands and runs them through a real gpulib implementation on a thread. Depending on a setting, it can either force a sync every frame, or continue to work until the next frame arrives.
