 * - #DNA_MAKESDNA defined:
 *   Defines store files with old names but run-time uses new names.
 *
 *   Allows us to rename variables & structs without breaking compatibility.
 *
 * - #DNA_MAKESDNA undefined:
 *   Behave as if old files were written new names.
 *
 *   This means older versions of Blender won't have access to this data *USE WITH CARE*.
