///
/// 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>;
///
/// Geometry:
/// <object>; <mesh>; <vertices>; <vertex>; <coordinates> and children <x>, <y>, <z>; <volume>; <triangle> and children <v1>, <v2>, <v3>;
