* Bound block expansion in drawing and extents (fixes #255)

MAX_BLOCK_DEPTH bounds only the depth of nested block references, so a
small DXF with a self-referencing block, blocks that each insert the next
several times, or one large MINSERT expanded to billions of copies and
hung the app (drawing, PNG/SVG/PDF export, extents, saving).

- render: a per-display-list budget (MAX_BLOCK_EXPANSION, 2 million
  block copies and entities drawn inside blocks); past it the remaining
  block contents are not drawn.
- doc: entity_bounds computes each block's content bounds once per call
  and reuses them for every further reference.

* Move Builder::expand below the drawing primitives

Pure code motion so this branch merges cleanly with fix/272-aci7-only-flips
(#272), which changes the Builder::polyline signature next to it.
