ps: Enable native encoding of subsurface patterns.

Carefully handle subsurfaces of a recording surface through the analysis
and paginated surfaces so that we can generate a native pattern for the
vector backends, demonstrated by the PostScript backend.

Nothing remarkable, just a lot of bookkeeping to track the wrapped
surface types and to apply the correct offsets when generating the
subsurface pattern.
