* - Old names aren't sanity checked (since this file is the only place that knows about them)
* typos in the old names will break both backwards & forwards compatibility **TAKE CARE**.
*
* - Before editing rename defines run:
*
* `sha1sum $BUILD_DIR/source/blender/makesdna/intern/dna.c`
*
* Compare the results before & after to ensure all changes are reversed by renaming
* and the DNA remains unchanged.
*
* \see versioning_dna.c for a actual version patching.
