// Minor parts of this file are extracts from blender data structures,
// declared in the ./source/blender/makesdna directory.
// Stuff that is not used by Assimp is commented.
// NOTE
// this file serves as input data to the `./scripts/genblenddna.py`
// script. This script generates the actual binding code to read a
// blender file with a possibly different DNA into our structures.
// Only `struct` declarations are considered and the following
// rules must be obeyed in order for the script to work properly:
//
// * C++ style comments only
//
// * Structures may include the primitive types char, int, short,
// float, double. Signedness specifiers are not allowed on
// integers. Enum types are allowed, but they must have been
// defined in this header.
//
// * Structures may aggregate other structures, unless not defined
// in this header.
//
// * Pointers to other structures or primitive types are allowed.
// No references or double pointers or arrays of pointers.
// A pointer to a T is normally written as boost::shared_ptr, while a
// pointer to an array of elements is written as boost::
// shared_array. To avoid cyclic pointers, use raw pointers in
// one direction.
//
// * Arrays can have maximally two-dimensions. Any non-pointer
// type can form them.
//
// * Multiple fields can be declare in a single line (i.e `int a,b;`)
// provided they are neither pointers nor arrays.
//
// * One of WARN, FAIL can be appended to the declaration (
// prior to the semiolon to specifiy the error handling policy if
// this field is missing in the input DNA). If none of those
// is specified the default policy is to subtitute a default
// value for the field.
//
#define WARN // warn if field is missing, substitute default value
#define FAIL // fail the import if the field does not exist
