hmm... I had an idea. Flashing happens very quickly. It also uses separate commands. Maybe I can do a rough page turn more quickly if I use FBIO_EINK_POSITIVEPIC instead of FBIO_EINK_DISP_NEWPIC.

Edit: Strange, I can't make the Reader flash using POSITIVEPIC and NEGATIVEPIC! In fact, when I issue EINK_NEGATIVEPIC and quit, the display turns inverse and stays inverse. All books, including those encoded by rasterfarian, become white-on-black, and the reader FLASHES WHITE.

I'm upset that I can't get the lightining page turns, but I think I just discovered something really cool! The white-on-black mode even makes reading easier on the eyes.

Also, double refreshes work well to reduce ghosting. In RasterReader I'll do a single refresh when turning pages quickly, then refresh a second time when it seems the user has settled on a page. (And refresh again later to keep the eink from fading.)
