/**
 * less's position table (position.c): one entry per screen row, holding
 * where that row STARTS.
 *
 * less's screen is not a top plus a wrapping rule - it is this array.
 * `position(sindex)` reads it, `add_forw_pos` drops the front and
 * appends, `add_back_pos` prepends, `pos_clear` empties it. Because
 * every row carries its own start, rows above and below a scroll seam
 * can sit on different grids, a row can begin mid-boundary, and a
 * width change simply regenerates the extents from the same starts.
 * Our `(row, subRow)` top could express none of that, which is what
 * config.subShift and config.subAnchor were bolted on to fake.
 *
 * Offsets count DISPLAY CHARACTERS, the space the layout's rowStart
 * indexes - never string indices, which differ on any styled line
 * because the layout keeps its escape codes in a separate list.
