How it works
Walk id-2 DVI instructions using their operand lengths, skipping font names and special payloads. Check bop/eop boundaries, stack framing and pre/postamble pointers.
The sample contains one page whose bop starts at byte 15 and points to -1. Its postamble states one page.
Limits
Uncompressed classic DVI id 2 up to 1 MB and 10000 pages. XDV and extended variants are rejected. Font metrics, glyph availability, drawing positions and special commands are not evaluated or executed; this is not a rendered-page or complete DVI validator.
