The current page is the page with the largest visible height. When more
than one row of pages is wholly on screen (a book with a portrait cover
and landscape spreads, at Fit Width or Fit Page), those heights differ
only by sub-point rounding after the scroll, so the "current" page was
whichever wholly visible page rounding favoured. ⌘Page Down then stepped
from the wrong spread: from the cover it went to 2–3 and then to 6–7,
skipping 4–5 (or, the other way round, stayed put after the cover).

Visible heights within half a point are now equal (the topmost wins),
and the page navigated to stays current while no page shows more of
itself, so the next step starts from it.

Test: viewer.rs::page_down_steps_every_spread_when_several_fit_on_screen
(a 12-page book with a cover page at Fit Width, Fit Page and Fit Height:
⌘Page Down visits 1, 3, 5, 7, 9, 11 and ⌘Page Up 9, 7, 5, 3, 1, 0).
Before the fix it went 1, 5, 7, 11, 11, 11 at Fit Width. Cited on the
view.cover-page parity entry.
