0.15.0: a set that arrived in parts says where the reader is Rest was a count and one address. It is a layout::Paging and up to two now, which is the same Window a carousel instantiates: a frame is a window of one over children that are present, a page is a window over rows that were never fetched, and presence shows up as whether there are addresses rather than as a second copy of the arithmetic. What this buys is that the description can say where the reader is at all. Position never reached it before, so a renderer could not print 'Page 3' even though that half is always knowable, and every screen kept it in app state instead. goingson's mail list ships prev/next and numbered pages and described itself as load-more. Each renderer draws one control for both jobs, and draws a direction it was given no address for as disabled rather than absent, so the pager keeps its width on the first page and the last. Slot::current delegates its clamp to Window for the same reason.
