- In various VSE related DNA structs, indicate which enums they use as comments, - Add enum types for the enums that were untyped, - Move Wipe effect enums to DNA header for clarity, since they are serialized values, - Reduce SeqRetimingKey size from 40 bytes to 32 bytes; there was too much unnecessary padding. - Rename some enums SEQUENCE_ -> STRIP_ where relevant. - Rename wipe enums DO_MEOW_WIPE -> SEQ_WIPE_MEOW Pull Request: https://projects.blender.org/blender/blender/pulls/143565
