That's actually already how it works. Bitmaps are rendered for up to 5 pages forward and 3 pages back (those bitmaps don't include the annotations). In the rendering engine, a certain number of pages are actually rendered on and off the screen depending upon which display mode is currently active. For the single page display, the current page, previous page and next page are all rendered and ready to go. So in theory, unless you are turning pages quickly and things are rendering quite slowly, each page should already be drawn when you turn the page.
