decode_r11: update HANDSEED on new handles
Fixes decoding and roundtrips of
e.g. r11/from_autocad_r12/sample/BASEPLAT.DWG
esp. on ctrl entries.
2024-02-09 Michal Josef Špaček <michal.josef.spacek@gmail.com>
Fix comments of ObjFreeSpace and SecondHeader
2024-02-08 Reini Urban <reini.urban@gmail.com>
bits: write only 4 byte handles on error
bits: sizeof bits union may be 16
detected by cppcheck. not sure which compiler actually does such things,
but keep it the specs
bits: fix leak
detected by cppcheck
decode_r11: accept 1 missing byte
esp. with TEXT entities. eg from_autocad_2.62/MENUTREE.DWG
there might be one more unknown byte
decode: cap handles at 32bit
Fixes GH #935, which has a r2000 example which has an undocumented high bit set
in most handles.
In fact, searching found no examples with more then 4 byte handles.
json-check: use min.json
dwg: support .min.json
json: support -m
json: option DWG_OPTS_MINIMAL for minJSON (minimized)
no whitespace at run-time.
We don't write minimal JSON as with minimal DXFs anymore

Fixes ASSOCGEOMDEPENDENCY dxf import with example_2000
(which was suppoed to be stable)
2024-02-06 Reini Urban <reini.urban@gmail.com>
dynapi: add dwg_dynapi_subclass_set_value
needed for indxf. can also be used for injson
gen-dynapi: fix ASSOCGEOMDEPENDENCY subclass
and fixup the lines for debugging
dxfb-check: harmonize with dxf-check
encode: fix ERROR: Wrong object size on MS adjust
when the new size doesnt fit the old MS size (overlarge MS size),
we move the stream by 2, but forgot to adjust the end_address calc,
leading to wrong ERROR: Wrong object size and CRC calc
XRECORD.cloning logging: print the DXF code
distcheck: cleanup check_oda files

2024-02-05 Reini Urban <reini.urban@gmail.com>
