///
/// Limitations.
///
/// 1. When for texture mapping used set of source textures (r, g, b, a) not only one then attribute "tiled" for all set will be true if it true in any of
/// source textures.
/// Example. Triangle use for texture mapping three textures. Two of them has "tiled" set to false and one - set to true. In scene all three textures
/// will be tiled.
///
/// Unsupported features:
/// 1. Node <composite>, formulas in <composite> and <color>. For implementing this feature can be used expression parser "muParser" like in project
/// "amf_tools".
/// 2. Attribute "profile" in node <color>.
/// 3. Curved geometry: <edge>, <normal> and children nodes of them.
/// 4. Attributes: "unit" and "version" in <amf> read but do nothing.
/// 5. <metadata> stored only for root node <amf>.
/// 6. Color averaging of vertices for which <triangle>'s set different colors.
///
/// Supported nodes:
/// General:
/// <amf>; <constellation>; <instance> and children <deltax>, <deltay>, <deltaz>, <rx>, <ry>, <rz>; <metadata>;

// 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. Signed 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 std::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 semicolon to specify the error handling policy if
// this field is missing in the input DNA). If none of those
// is specified the default policy is to substitute a default
// value for the field.
//
// warn if field is missing, substitute default value
