* Extents: ignore rays and references to missing or empty blocks, as ZOOM Extents does Opening real drawings in CADCraft often showed a tiny plan in a huge empty canvas, because the extents included things that draw nothing: - the base point of a RAY (Autodesk's own reference says infinite construction lines and rays do not affect ZOOM Extents; an office plan in our corpus carries two rays 1.98 million units from the building); - the insertion point of an INSERT whose block is missing (a purged definition, a bound xref that never came along) or empty (an unloaded xref): a floor plan had such references 125 000 and 3.4 million units away. XLINEs were already ignored; rays now are too, and an insert contributes only what its block draws (attributes still count). Two regression tests use the measured coordinates.

Dynamic blocks keep hidden constraint geometry far from the visible part. - Text/MText that is empty, whitespace-only or only "\~" has empty bounds. - Tests cover each rule separately.
