We cycle through displaying the buffers at roughly 12 frames per second- a familiar speed for limited animation- though the drawing itself is processed more responsively. Three frames is something of a sweet spot: using only two frames produces an unpleasant jittering effect, and more than three frames offer a diminishing addition of fluidity:，这一点在谷歌浏览器下载中也有详细论述

and this is the crux of why we care: extended operators do not make sense with an ordered OR. if | isn’t commutative, then boolean algebra falls apart.
