pauliusiv123-rgb 4d358d4fa4 M2: a /Rotate that isn't a quarter turn counts as 0, as the page is drawn (#1863) ...

Page::rotation rounded a /Rotate that isn't a multiple of 90 down to a
quarter turn (135 became 90), while the renderer draws such a page
upright. Display size and the display-to-user-space matrix (header and
footer, watermarks, measuring, printing, image signatures) then
disagreed with the page on screen. ISO 32000-2 §7.7.3.3 requires a
multiple of 90; read any other value as 0, as the renderer does.

Page import and image stamps, which read /Rotate themselves, already
treat such a value as 0. Test: rotate_off_a_quarter_turn_counts_as_upright
(/Rotate 135, 30, -45, 359).
