It's required for interfacing dynamic languages to provide a better dynamic API, and for the importers, a precompiled list or hash of all known elements, objects and subtypes with all its properties.
These can be generated via processing the dwg.h or dwg.spec into gperf hashes or arrays.
The needed info per field would be: name, type, offsetof(), (dxf).

Then we could also implement a dwgfilter program (#64), which allows filtering on user-defined, dynamic objects and it's properties. e.g. dwglayer, dwgxrefs, ...
analog to osmfilter

we could also get rid of the massively big and unmaintainable dwg_api functions, replacing it with the dynamic versions, separated by type. and add a reflective api, e.g. return the VERTEX_2D fields, the type of the VERTEX_3D.point field, ...

  • rename dwg_get_OBJECT(dwg) to dwg_getall_OBJECT(dwg)
  • rename dwg_get_ENTITY(blkhdr) to dwg_getall_ENTITY(blkhdr)
  • add dwg_get_OBJECT(obj, field) field getters by string (single field only)
  • add dwg_set_HEADER(dwg, field, value, ...), dwg_set_OBJECT(obj, field, value, ...) set multiple fields.
    e.g. for 3RD: dwg_set_VERTEX_2D(obj, "point", 0.0, 0.0, 1.0);

api: convert IMAGE.size.{width,height} to 2RD

no inline structs in WIPEOUT and IMAGE.
convert inline struct { width; height } to 2RD (x,y).
The size is documented as size (u,v),
not width/height in the AutoCAD DXF docs.

This is mostly to simplify the dynapi #59

dynapi getters finished with 2d7220d
dynapi setters finished with 47386de
(still yet unused, just tested)

TODO:

  • switch over dwg_api to use it (and deprecate/delete most static funcs)
  • add a dxfgroup field and search for it. (for dxfin)
  • add convenience api (with obj, not ent/_obj) as described
  • add dynapi for common_data fields (and handles)
  • some dynamic arrays either need a size arg (eg. INSERT.attrib_handles H*) or just work with the ptr on the array. is_malloc 1, is_indirect, is_string (for null-terminated strings)
