fix(layout): place a window-plot sheet around its plot window

A layout plotted by window drew its sheet at the paper-space origin, so
the title block sat on the grey background away from the paper. The
sheet now centres on the plot window, or sits at the plot offset from it
when the plot is not centred.

Bump codec 8aa574a (polyline vertices in owned-handle order, which fixes
self-crossing viewport clip boundaries), kernel d79bb30, graph 4810ee0.

Fixes #1678
