- Run the `wp_generate_attachment_metadata` filter at the end in `wp_update_image_subsizes()` when new metadata was generated and additional image sub-sizes were created.
- Add another arg in the `wp_generate_attachment_metadata` filter for additional context.
- Fix inline docs and ensure the new image meta is always saved before starting post-processing.
