Pause doc: Pages drawing (#2190)

* name main fields and regs for pages drawing

* comments

* format

* more comments

* roll -> pitch (oops)

* Document `PauseContext.offsetY`, `R_PAUSE_OFFSET_VERTICAL` as "y origin 1/2"

* copypaste comment on page pitches fields

* "offset depth" -> "depth offset"

* review
