C3D-0416 · READ-ONLY: vicinity label positions, existing rasters, title-block frames [C3D-VICSTATE] done

Per layout: the VICINITY MAP label extents, any existing RasterImage (with source path), the SS_BLOCK frame extents, and whether the image dictionary / embed xrecord exist. Needed to place the vicinity map correctly and idempotently.
