/* render_queue is modified both by this and its associated thread without mutexes, this is intentional.
* reason being that since rendering is done in the same thread as the logic,
* using mutexes actually slows this down more than the result of an unknown state.
* an unknown state may be an incomplete render, which in my tests wont crash, or one too many renders.
* both of these chances are non distructive.
* doing rendering async is done because
* A: its funny
* B: previous render pipelines may have caused win_r to lack behind
* C: slowdown as a result of too many renders */
